Minor typos

Just looking at the docs for the first time and noticing a few readability issues with the module description:

smol_str/src/lib.rs

Line 22 in 7d1b60c

/// * `size_of::<SmolStr>() == 24 (therefor == size_of::<String>() on 64 bit platforms)

It's "therefor" instead of "therefore".

The ::<SmolStr> and ::<string> doesn't show up on the crate docs either:

Reading this (rust-lang/rust#18419), it sounds like you need to escape the < and < since they are HTML. Probably just < and >.

No that was just missing a backtick see #59 😄
