Allow for clap to parse argument values into types

This changes

- `.flag`, `.option`, `.options` and `.positionals` are now just fields
  you access on the result of `parse` and `parseEx`.
- `clap.ComptimeClap` has been removed.
- `clap.StreamingClap` is now called `clap.streaming.Clap`
- `parse` and `parseEx` now takes a `value_parsers` argument that
  provides the parsers to parse values.
- Remove `helpEx`, `helpFull`, `usageEx` and `usageFull`. They now just
  expect `Id` to have methods for getting the description and value
  texts.
