Now based on titanous/json5 package instead of yosuke-furukawa/json5 
This is a Go package that implements decoding of JSON5. See the documentation for usage information.
- The tag being used is
json5instead ofjson - merged the patch from
skybosito support autoconvert string to number, added more tests
