chore(deps): bump regex from 0.2.11 to 1.3.9

[dependabot]

Bumps regex from 0.2.11 to 1.3.9.

Release notes

Sourced from regex's releases.

1.0.0

This release marks the 1.0 release of regex.

While this release includes some breaking changes, most users of older versions of the regex library should be able to migrate to 1.0 by simply bumping the version number. The important changes are as follows:

• We adopt Rust 1.20 as the new minimum supported version of Rust for regex. We also tentativley adopt a policy that permits bumping the minimum supported version of Rust in minor version releases of regex, but no patch releases. That is, with respect to semver, we do not strictly consider bumping the minimum version of Rust to be a breaking change, but adopt a conservative stance as a compromise.
• Octal syntax in regular expressions has been disabled by default. This permits better error messages that inform users that backreferences aren't available. Octal syntax can be re-enabled via the corresponding option on RegexBuilder.
• (?-u:\B) is no longer allowed in Unicode regexes since it can match at invalid UTF-8 code unit boundaries. (?-u:\b) is still allowed in Unicode regexes.
• The From<regex_syntax::Error> impl has been removed. This formally removes the public dependency on regex-syntax.
• A new feature, use_std, has been added and enabled by default. Disabling the feature will result in a compilation error. In the future, this may permit us to support no_std environments (w/ alloc) in a backwards compatible way.

For more information and discussion, please see 1.0 release tracking issue.

Changelog

Sourced from regex's changelog.

1.3.9 (2020-05-28)

This release fixes a MSRV (Minimum Support Rust Version) regression in the 1.3.8 release. Namely, while 1.3.8 compiles on Rust 1.28, it actually does not compile on other Rust versions, such as Rust 1.39.

Bug fixes:

• [BUG #685](rust-lang/regex#685): Remove use of doc_comment crate, which cannot be used before Rust 1.43.

1.3.8 (2020-05-28)

This release contains a couple of important bug fixes driven by better support for empty-subexpressions in regexes. For example, regexes like b| are now allowed. Major thanks to @sliquister for implementing support for this in #677.

Bug fixes:

• [BUG #523](rust-lang/regex#523): Add note to documentation that spaces can be escaped in x mode.
• [BUG #524](rust-lang/regex#524): Add support for empty sub-expressions, including empty alternations.
• [BUG #659](rust-lang/regex#659): Fix match bug caused by an empty sub-expression miscompilation.

1.3.7 (2020-04-17)

This release contains a small bug fix that fixes how regex forwards crate features to regex-syntax. In particular, this will reduce recompilations in some cases.

Bug fixes:

• [BUG #665](rust-lang/regex#665): Fix feature forwarding to regex-syntax.

1.3.6 (2020-03-24)

This release contains a sizable (~30%) performance improvement when compiling some kinds of large regular expressions.

Performance improvements:

• [PERF #657](rust-lang/regex#657):
