feat: add dataset table

[ozym]

This adds a simple domain and network lookup table, it also allows for a reference citation and whether it is used in tilde

looks good, thanks @ozym , that's awesome!! I haven't fully reviewed the code, so would be great if someone from @GeoNet/ssd-team can also review

question: assume this is because when decoding, you want to produce the exact same input, i.e. "True" -> "True", "TRUE" -> "TRUE" etc.?

[ozym]

yes, that's on the money. It's mostly used for floating point numbers, e.g. input is 1.00 which then would go to 1.0 on output and then flag there's something different when running tests.

It's a shame Go doesn't allow for optional parentheses for no argument functions, otherwise you could make Tilde be a function that returns bool based on the value of tilde. But since it is required, making it into a function is a little ugly, as you'd be calling d.Tilde(), and other values d.Domain. You do get to remove a mutable variable though.
Still, I'm happy with this, thanks for the context.
