* allow dynamic block size in cache
allow block size to be variable/dynamic
update lrucache to use updated lrucache dep
Using removeLru proc, added tests
* Refactor CacheStore init block

This PR achieves the following:
1. Improves the exception handling when dialling a peer fails or an unknown error occurs.
2. Add a `Content-Type` header to the `/download` endpoint of `application/octet-stream`, which is [defined by MDN](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types#types) as meant to be used for "generic binary data (or binary data whose true type is unknown)".

Integrate dagger contracts from `nim-dagger-contracts` repo.
Add `dagger-contracts`, `nim-web3`, and all of `nim-web3`’s transitive deps as submodule deps to `nim-dagger`. Note: `nim-web3` and its transitive deps may no longer be needed when we switch to `nim-ethers`.
Add a `testContracts` nimble task to test all of the contracts functionality. Namely, this spins up an ethereum simulator, deploys the contracts (in `dagger-contracts`), runs the contract tests, and finally, regardless of success/error, kills the ethereum sim processes. The nimble task can be run with `./env.sh nimble testContracts`.
We also tested `nim-dagger-contracts` as a submodule dep of `nim-dagger`, and while the tests run as expected, the preference is to merge `nim-dagger-contracts` inside of `nim-dagger` for ease of parallel development. There’s also a high probability that `nim-dagger-contracts` is not being used as a dep by other projects. Are there any strong objections to this?

Downloading a CID that is unknown to the network would wait for the blockexchange to try to get the data. However, a subsequent API call, eg upload for that CID, or a blockexchange timeout would cause the dagger node to crash, due to an attempt to complete a future that had already been completed.
We were able to narrow this down to an attempt to call `resp.finish()` when the download block had already returned an `RestApiResponse` (and never sent any chunks to the response from the libp2p stream).
Change the HTTP response code for an unknown cid from 400 to 404.
Fix spelling mistake “cunk”.
