Add a port to .NET

[kevin-montrose]

Maintains roughly the same internal structure, including tests and benchmarks.

Targets .NET Standard & Core. C# 7.2.

No work on optimization or "idiomizing" yet, just getting to parity.

There are considerable changes to repo structure here, so I'm not expecting this to get merged. Rather it's a point for discussion and review.

Looks good, ran successfully on my machine (Mac, .Net Core 2.1). One test fails.

For merging, do we want .Net in the same repo as Go? Might be kinda fun and good for sharing test data.

Happy to chat about how we’d like to organize the code in a more .Net-ish way.

See comment on PR. LGTM and I ran it successfully on my machine. I don’t know if the .Net code should live in this repo or whether we want to rewrite.

[kevin-montrose]

Gonna tell me which test fails?

[clipperhouse]

The Go package needs to be at the top level, moving it down under go/ will break import paths.

[clipperhouse]

This is looking really good.

We can merge this in if you are happy with it. As I mentioned, we can’t have the go/ subdirectory — so I’ll let you do whatever git fu you need to do.

Might just cherry pick the .Net commits into a new branch — or even just copy pasta the dotnet directory as a new commit against master, if you don’t care about the commit history.

I've still got a few more rough edges I want to sand off, then I'll probably just close this and submit a new PR w/o history. Want to chat about directory structure sometime, maybe this weekend.
