Reduce dependency bloat

[Kixiron]

• Started trying to remove num from the dependency tree
• Removed some of the "default dependencies" from generated crates, this should allow better compilation scheduling since crates don't have to wait on unnecessary dependencies
• Discovered that some files are in CLRF form, this will be fixed in a later PR
• Removed dependencies on fnv and twox-hash and replaced with a single dependence on xxhash-rust, it has zero dependencies and is very light
• Removed old dependence on time for all generated crates, this reduced the dependency tree a good bit
• Minor refactors to some massive match statements
• Added some documentation to the DDVal/DDValue innards

Some of these files show every line as different. Is this due to CR/LF? This makes it hard to review.

[Kixiron]

Yes, those are files that were changed from CLRF to LF, I'll make a PR that bites the bullet and standardizes things after this. In the diff view select the Hide Whitespace option to ignore the line ending changes
