chore(deps): bump regex from 1.4.1 to 1.5.3

[dependabot]

Bumps regex from 1.4.1 to 1.5.3.

Changelog

Sourced from regex's changelog.

1.5.3 (2021-05-01)

This releases fixes a bug when building regex with only the unicode-perl feature. It turns out that while CI was building this configuration, it wasn't actually failing the overall build on a failed compilation.

• [BUG #769](rust-lang/regex#769): Fix build in regex-syntax when only the unicode-perl feature is enabled.

1.5.2 (2021-05-01)

This release fixes a performance bug when Unicode word boundaries are used. Namely, for certain regexes on certain inputs, it's possible for the lazy DFA to stop searching (causing a fallback to a slower engine) when it doesn't actually need to.

[PR #768](rust-lang/regex#768) fixes the bug, which was originally reported in ripgrep#1860.

1.5.1 (2021-04-30)

This is a patch release that fixes a compilation error when the perf-literal feature is not enabled.

1.5.0 (2021-04-30)

This release primarily updates to Rust 2018 (finally) and bumps the MSRV to Rust 1.41 (from Rust 1.28). Rust 1.41 was chosen because it's still reasonably old, and is what's in Debian stable at the time of writing.

This release also drops this crate's own bespoke substring search algorithms in favor of a new memmem implementation provided by the memchr crate. This will change the performance profile of some regexes, sometimes getting a little worse, and hopefully more frequently, getting a lot better. Please report any serious performance regressions if you find them.

1.4.6 (2021-04-22)

This is a small patch release that fixes the compiler's size check on how much heap memory a regex uses. Previously, the compiler did not account for the heap usage of Unicode character classes. Now it does. It's possible that this may make some regexes fail to compile that previously did compile. If that happens, please file an issue.
