Bumps regex from 1.3.7 to 1.4.3.

Changelog

Sourced from regex's changelog.

1.4.3 (2021-01-08)

This is a small patch release that adds some missing standard trait implementations for some types in the public API.

Bug fixes:

• [BUG #734](rust-lang/regex#734): Add FusedIterator and ExactSizeIterator impls to iterator types.
• [BUG #735](rust-lang/regex#735): Add missing Debug impls to public API types.

1.4.2 (2020-11-01)

This is a small bug fix release that bans \P{any}. We previously banned empty classes like [^\w\W], but missed the \P{any} case. In the future, we hope to permit empty classes.

• [BUG #722](rust-lang/regex#722): Ban \P{any} to avoid a panic in the regex compiler. Found by OSS-Fuzz.

1.4.1 (2020-10-13)

This is a small bug fix release that makes \p{cf} work. Previously, it would report "property not found" even though cf is a valid abbreviation for the Format general category.

• [BUG #719](rust-lang/regex#719): Fixes bug that prevented \p{cf} from working.

1.4.0 (2020-10-11)

This releases has a few minor documentation fixes as well as some very minor API additions. The MSRV remains at Rust 1.28 for now, but this is intended to increase to at least Rust 1.41.1 soon.

This release also adds support for OSS-Fuzz. Kudos to @DavidKorczynski for doing the heavy lifting for that!

New features:

• [FEATURE #649](rust-lang/regex#649): Support [, ] and . in capture group names.
• [FEATURE #687](rust-lang/regex#687): Add is_empty predicate to RegexSet.
• [FEATURE #689](rust-lang/regex#689):
