### Description
Add bug reporting issue template and template for proposing a "Summer of Bitcoin" project.
### Notes to the reviewers
The SoB template is basically a copy of what Adi created but lightly formatted to work as github issue templates.

2fc8114180 moving the function wallet_name_from_descriptor from blockchain/rpc.rs to wallet/mod.rs as it can be useful not only for rpc (Richard Ulrich)
Pull request description:
### Description
Moving the function wallet_name_from_descriptor from rpc.rs to mod.rs
Since the local cache for compact filters should be separate per wallet, this function can be useful not only for rpc.
### Notes to the reviewers
I thought about renaming it, but waited for opinions on that.

Pull request description:
## Description
This PR does dependency inversion on the previous sync logic for electrum and esplora captured in the trait `ElectrumLikeSync`. This means that the sync logic does not reference the blockchain at all. Instead the blockchain asks the sync logic (in `script_sync.rs`) what it needs to continue the sync and tries to retrieve it.
The initial purpose of doing this is to remove invocations of `maybe_await` in the abstract sync logic in preparation for completely removing `maybe_await` in the future. The other major benefit is it gives a lot more freedom for the esplora logic to use the rich data from the responses to complete the sync with less HTTP requests than it did previously.
## List of changes
- sync logic moved to `script_sync.rs` and `ElectrumLikeSync` is gone.
- esplora makes one http request per sync address. This means it makes half the number of http requests for a fully synced wallet and N*M less requests for a wallet which has N new transactions with M unique input transactions.
- electrum and esplora save less raw transactions in the database. Electrum still requests input transactions for each of its transactions to calculate the fee but it does not save them to the database anymore.
- The ureq and reqwest blockchain configuration is now unified into the same struct. This is the only API change. `read_timeout` and `write_timeout` have been removed in favor of a single `timeout` option which is set in both ureq and reqwest.
- ureq now does concurrent (parallel) requests using threads.
- An previously unnoticed bug has been fixed where by sending a lot of double spending transactions to the same address you could trick a bdk Esplora wallet into thinking it had a lot of unconfirmed coins. This is because esplora doesn't delete double spent transactions from its indexes immediately (not sure if this is a bug or a feature). A blockchain test is added for this.
- BONUS: The second commit in this PR fixes the feerate calculation for esplora and adds a test (the previous algorithm didn't work at all). I could have made a separate PR but since I was touching this file a lot I decided to fix it here.
## Notes to the reviewers
- The most important thing to review is the the logic in `script_sync.rs` is sound.
- Look at the two commits separately.
- I think CI is failing because of MSRV problems again!
- It would be cool to measure how much sync time is improved for your existing wallets/projects. For `gun` the speed improvements for modest but it is at least hammering the esplora server much less.
- I noticed the performance of reqwest in blocking is much worse in this patch than previously. This is because somehow reqwest is not re-using the connection for each request in this new code. I have no idea why. The plan is to get rid of the blocking reqwest implementation in a follow up PR.

Now works with latest released versions of rust-bitcoincore-rpc and
bitcoind. Once these crates are updated to support creating descriptor
wallets and add importdescriptors and bech32m support this test will
need to be updated.
