1.1.3

• Fix a bug reported in #27.
  • Before the patch, jkj::dragonbox::to_decimal could return a struct with an uninitialized member if jkj::dragonbox::policy::binary_to_deciaml_rounding::do_not_care policy is set.
  • jkj::dragonbox::policy::binary_to_deciaml_rounding::do_not_care is not the default policy so code using the default policy for binary-to-decimal rounding is not affected.
• Improve documentation/comments.
• Improve CI.
