b866236aad fix: mpc_sepby1 not applying fold correctly 
`mpc_sepby1` takes a single fold function but this doesn't apply to the
whole list of entries. Instead it applies the fold twice,
one for `mpc_and` and another for `mpc_many`.

Introduce a new repeat repeat parser type MPC_TYPE_SEPBY1 that combines
the results and applies the fold once for all entries.

21286d5915 refactor: deduplicate repeat parsers alloc logic 
Deduplicates the results allocation logic used in MPC_TYPE_MANY
and MPC_TYPE_MANY1 on a `grow_results` function.

This will aid in implementing new repeat parser types. A new one is
neeeded for `sepby1` as discussed on
https://github.com/orangeduck/mpc/pull/165#discussion_r1292878771.

c24e27f0b8 feat: add sepby1 combinator 
`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`.

6f5e8f0f39 Fix backtracing bug with mpc_parse_pipe 
Before we free our buffer we need to reset the underlying stream to its
original state by pushing the buffer contents back onto the input
stream.

Fixes #109

6c03383cd1 Cast argument to unsigned char before feeding to ctype.h functions 
The behavior of the `<ctype.h>` functions is undefined for negative
arguments (other than `EOF`). In such a situation, the argument should
be cast to `unsiged char` for safety.
