Bumps tzlocal from 2.1 to 4.3.

Changelog

Sourced from tzlocal's changelog.

4.3 (2023-03-18)

• Improved the error message when the ZoneInfo cannot be found

• Don't error out because we find multiple possible timezones for a symlink.

• More stable on Android/Termux with proot

4.2 (2022-04-02)

• If TZ environment variable is set to /etc/localhost, and that's a link to a zoneinfo file, then tzlocal will now find the timezone name, and not just return a localtime TZ object.

4.1 (2021-10-29)

• No changes from 4.1b1.

4.1b1 (2021-10-28)

• It turns out a lot of Linux distributions make the links between zoneinfo aliases backwards, so instead of linking GB to Europe/London it actually links the other way. When /etc/localtime then links to Europe/London, and you also have a config file saying Europe/London, the code that checks if /etc/localtime is a symlink ends up at GB instead of Europe/London and we get an error, as it thinks GB and Europe/London are different zones.

  So now we check the symlink of all timezones in the uniqueness test. We still return the name in the config file, though, so you would only get GB or Zulu returned as the time zone instead of Europe/London or UTC if your only configuration is the /etc/localtime symlink, as that's checked last, and tzlocal will return the first configuration found.

• The above change also means that GMT and UTC are no longer seen as synonyms, as zoneinfo does not see them as synonyms. This might be controversial, but you just have to live with it. Pick one and stay with it. ;-)

4.0.2 (2021-10-26)

• Improved the error message when you had a conflict including a
