feat(store): add waku store client module

[LNSD]

The waku store protocol is a request-response/client-server protocol. These changes decouple the client logic from the request-handling logic. So now it should be possible to do waku store history queries without mounting the store protocol handling/server part.

• Move waku store client logic to waku_store/client module
• Deprecate waku store protocol client procedures
• Use waku store client in waku store unit tests
• Extend coverage of waku store client code (see tests/v2/test_waku_store_client.nim)

Remaining work:

• Use the waku store client in wakunode2/waku_node.
• Remove waku store protocol deprecated methods.

[alrevuelta]

looks great!

[alrevuelta]

out of curiosity, why do you need a copy?

[LNSD]

To update the cursor field, and keep the rest of the request intact. This part of the implementation has not been changed compared to the original protocol.nim code.

[jm-clius]

LGTM! Can't wait to not mount store protocol on store clients which ultimately allows us to greatly simplify config.
