feat: add sepby1 combinator

Browse Source 
`sepby1` is a common reusable combinator in Haskell Parsec.

This adds `mpc_sepby1(mpc_fold_t f, mpc_parser_t *sep, mpc_parser_t *a)` according to Haskell's implementation:

https://hackage.haskell.org/package/parsec-3.1.16.1/docs/src/Text.Parsec.Combinator.html#sepBy1

Reuses existing `mpc_and`, `mpc_many`, and `mpcf_snd_free`.
