[chronik client + ecash-herald + token-server + cashtab + ecash-lib + ecash-agora] Deprecate NNG support from chronik-client

Summary:
chronik was first developed on a bitcoin abc fork. It was later improved to work directly with the abc node in the monorepo.

This improved version was planned to be the only / default version.

Get rid of nng support. Rename all "InNode" types to lose this special marker. Rename ChronikClientNode to ChronikClient

Bump chronik-client to 1.0.0

Update ecash-herald, token-server, and Cashtab to handle this new type.

Note: alias-server and apps/examples are still legacy chronik nng apps. alias-server will be migrated to in-node if it is to be used for aliases. app/examples needs some thought. Potentially should be deprecated as the integration tests in chronik-client are more exhaustive, accurate, and easier to maintain.

I considered a phased approach where, say, we do not change all the names. I think though it is best to just drop this stuff, since there is no plan to maintain nng support going forward, and full migration to in-node was always the plan.

Test Plan:
CI

To test existing implementations can still import and use ChronikClientNode

• cd modules/chronik-client and npm run build
• cd cashtab and npm start, send a tx, no API error
• In cashtab/src/index.js, replace ChronikClient with ChronikClientNode
• npm start, send a tx, no API error
