Update to 1.05

Upstream changes:
1.05 - Todd Rinaldo <toddr@cpan.org> 2020-12-11
- Additional tests for known corner cases.
- Use Perl_warn not warn in XS.
- Test cleanup. Abstract helper calls.
- Macro cleanup in XS for code readability.

1.04 - Todd Rinaldo <toddr@cpan.org> 2020-12-10
- add utf8 mode for read/write of database
- Major re-factor to remove SVs from the CDB internals. SVs are only generated at return.
  This was in attempt to address a known memory leak in the previous implementation.
- CDB_File will warn if undef keys or values are passed to insert. This is meant to be
  consistent with how Perl handles the situation.
- Consistently tidy CDB_File.xs and remove tabs
- Make unit tests use File::Temp so we don't leave temp files laying around
- update Devel::PPPort to 3.62

1.03 - Todd Rinaldo <toddr@cpan.org> 2020-11-13
WARNING: due to a bug (#12) on 1.02, CDB databases generated by 1.02 will
not be legible by all other versions and vice-versa. It is recommended you
re-generate any databases generated by that version.

- #12 Fix incompatibility with CDB files due to accidental algorithm change.
  Add xt tests for 0.96 databases to assure this does not happen again.
- Fixup Changelog for metacpan
- #11 Add additional benchmark test in git for.
- Provide the CDB_File algorithm in POD in the event the original document is lost.
- Update Devel::PPPort to 3.54
