chore: update readme

In the README, example variable names for `lndk.conf` were incorrect.
They need to be snake_case rather than kebab-case.

Specifically:
`cert-path` --> `cert_path`
`macaroon-path` --> `macaroon_path`

This commit updates the README with the proper variable names.

Additionally, this commit changes the wording for clarity by specifying
LNDK "features" rather than "options".

 LNDK is a standalone daemon that connects to [LND](https://github.com/lightningnetwork/lnd) (via its grpc API) that aims to implement [bolt 12](https://github.com/lightning/bolts/pull/798) functionality _externally_ to LND. LNDK leverages the [lightning development kit](https://github.com/lightningdevkit/rust-lightning) to provide functionality, acting as a thin "shim" between LND's APIs and LDK's lightning library.
