consider making new networkadapters exported in their own package

[mr-zwets]

By having adapters in their own package they could be versioned separately from the main branch

it would also avoid all adapters and their dependencies being part of the source code (without bundling/tree shaking)

[mr-zwets]

instead of making this a breaking in the v0.11.0 release, we could start doing this for the new networkProviders planned in v0.11.1 and then externalize the FullStackNetworkProvider and BitcoinRpcNetworkProvider providers as their own package
