Single JTAF binary proposal

[davedotdev]

I propose a single JTAF binary which consumes both individual JTAF programs. This is mainly to make the user journey simpler and build steps.

Usage
Users would compile a single binary and instantiate it with flags which activate a code path. For example, to generate the YANG XPath expressions:

./jtaf -processYang -config ./config.toml

Similarly, to process the provider:

./jtaf -processProvider -config ./config.toml

It would be simple to create a single JTAF binary and add flags to control internal flow. The result would be a single application instead of two separate binaries.

Let's discuss here. I'm happy to take this on if there is agreement. This would also act as a foundation for other work as we add features.
