skipFailures: boolean | axe.ImpactValue[] = false -- allow handling imacts

[mwmcode]

Hello,

Can we have skipFailures accept array of impacts to skip (log/warn)? (so it'd be skipFailures: boolean | axe.ImpactValue[] = false)

Currently it either skips/logs all violations or asserts all.

There are scenarios where one might want to see warnings for certain impact violations while letting other violations fail the test if they are not met.
For example: log warning about color-contrast but fail when missing aria-label

This should be covered by the shouldFail option in the new API: #75

I have actually read/upvoted that already but somehow missed the shouldFail part. Looks neat, any release date estimation?

Re-openning for consideration (since it's not a breaking change, and might also be a bridge to the next release where passing callback will be the way to handle assertion failures), since the next major release doesn't seem to be coming soon?
