Update to tskit C API 1.0.0

[benjeffery]

Fixes #2060
Took the liberty of removing the git submodule in the process.

It's not obvious that removing the submodule is better here - won't we have to manually vendor in tskit every time we update then?

Yes, but we had to update the submodule anyway - I know which one gives me less hassle! Your call!

Hmm the LWT is the fly in the vendoring ointment. Probably easiest to keep the submodule.

I'm sure I went round this one a few times relatively recently and decided the submodule was the lesser of n evils

[benjeffery]

This cannot proceed until the next tskit python release as the LWT tests fail when used against tskit 0.4.1.

This should be good to pick up now @benjeffery?
