Embed strkey CLI command for encoding and decoding address strings (#2324)

### What
Upgrade stellar-strkey from 0.0.13 to 0.0.15, enable the cli feature,
and add a new `strkey` subcommand to the CLI.

### Why
Expose strkey encoding and decoding functionality directly in the CLI,
matching the existing pattern used for XDR. For advanced use cases it is
helpful to be able to extract components out of addresses. The use cases
this is most relevant is cross-chain protocols who prefer to work with
the raw payloads within the addresses.
