chore(deps): bump regex from 1.4.3 to 1.4.5

[dependabot]

Bumps regex from 1.4.3 to 1.4.5.

Changelog

Sourced from regex's changelog.

1.4.5 (2021-03-14)

This is a small patch release that fixes a regression in the size of a Regex in the 1.4.4 release. Prior to 1.4.4, a Regex was 552 bytes. In the 1.4.4 release, it was 856 bytes due to internal changes. In this release, a Regex is now 16 bytes. In general, the size of a Regex was never something that was on my radar, but this increased size in the 1.4.4 release seems to have crossed a threshold and resulted in stack overflows in some programs.

• [BUG #750](rust-lang/regex#750): Fixes stack overflows seemingly caused by a large Regex size by decreasing its size.

1.4.4 (2021-03-11)

This is a small patch release that contains some bug fixes. Notably, it also drops the thread_local (and lazy_static, via transitivity) dependencies.

Bug fixes:

• [BUG #362](rust-lang/regex#362): Memory leaks caused by an internal caching strategy should now be fixed.
• [BUG #576](rust-lang/regex#576): All regex types now implement UnwindSafe and RefUnwindSafe.
• [BUG #728](rust-lang/regex#749): Add missing Replacer impls for Vec<u8>, String, Cow, etc.

I'm getting the feeling that the benches still have some undesired noise. I reran them on a benchmark runner and got, for just regressions:
