Small parser combinator library

`lib.rs`:

Minimal parser combinators

Basic parsers

Items	Description	Example
[`and`]	Combine two parsers where both must succeed.	`and(u16l, u32l)`
[`or`]	Combine two parsers where at least one must succeed.	`or(u16l, u32l)`
`take`	Take N bytes.	`take(42)`
[`seq`]	Run a parser N times in sequence.	`seq(u32l, 42)`
[`tag`]	Match a sequence of bytes.	`tag("hello")`
[`opt`]	Allow a parser to fail.	`opt(tag("hello"))`
[`pod`]	Transmute bytes into a type. Requires the `bytemuck` feature	`seq(pod::<MyType>, 4)`
`finish`	Ensure there is no bytes left	`finish(seq(u16l, 128))`

Number parsers

	`u8`	`u16`	`u32`	`u64`	`u128`	`f32`	`f64`
Little Endian	`byte`	`u16l`	`u32l`	`u64l`	`u128l`	`f32l`	`f64l`
Big Endian	`byte`	`u16b`	`u32b`	`u64b`	`u128b`	`f32b`	`f64b`
