am running pact-go 2.x.x branch and v3 matchers. the header matching seems to be always doing a strict match. is that expected? for example, given this:

Header("x-b3-spanid", matchers.Like("flexible")).

The pact has:

x-b3-spanid": "flexible",

And then running yields:

1.1) includes header 'x-b3-spanid' with value 'flexible'
           Expected header 'x-b3-spanid' to have value 'flexible' but was 'bee11777fdc9b79c'

hmm it shouldn’t

opened an issue with the diff to apply to the example test to reproduce: https://github.com/pact-foundation/pact-go/issues/281
