Change log for the Getopt::Std Raku module

1.0.2

• Rename the files using Raku extensions.

• Add some more fields to the META6.json file.

• Declare the API version in the module itself.

  1.0.1

• Support non-alphanumeric characters as option characters, e.g. let a "-:" option string be used to sort of support long options such as "--help" and "--version".

  1.0.0

• Do not error out on an empty option string if the :unknown or :nonopts flags are specified.

• Throw an X::Getopt::Std exception instead of returning false. Incidentally, closes: #2; thanks, Tom Browder!

• Stop exporting two internal utility functions even if :util is specified when importing the module.

• Skip the :unknown :!all cases in the test suite.

• Remove the :all flag and split it out into the getopts-all() function instead, if only to be able to predict the type of the returned options array. Closes: #1; thanks, Tom Browder!

• Update the Travis CI build:

  • build on the 2017.{06,07,08,09} Rakudo Perl 6 releases

  • do not test building with "panda"

• Merge Samantha McVey's pull request #1 to specify the Artistic-2.0 license in META6.json.

  0.1.0

Initial public release.
