ambiguous step def detection akin to cucumber jvm (#636)

* added basic detection for ambiguous steps, but causes an error and not yet recorded in the reports as 'Ambiguous', and no test cases figured out yet

* added initial support for detection of ambiguous steps - further work take a look at how cuke jvm report ambiguous steps and sets the step status to 'ambiguous' rather than my current solution which just blows the test up as a regular step error

* added suite_context_test and also introduced missing 'ambiguous' status to make cucumber jvm'

* update CHANGELOG for ambiguous step defs

* missed file from commit

* added internal/formatters/fmt_multi_test.go

* add tests for other peoples code

* added "ambigous" to the help text

* tests

* added some more tests for attachments

* Update internal/flags/flags.go
