Feature: Non-exhaustive Matching Mode

[fbartho]

Fixes #72

Since the way we parse text in this library basically implies the global flag is always enabled, we've had a request for non-global mode.

The way to enable it is by passing nonExhaustiveModeMaxMatchCount: 1 as an extra prop for your parse pattern configuration.

If you want, you can change the number higher to accept a certain number of matches, and then stop.
For Example: if you were going to give URL previews, but only to the first 2 URLs in a given chunk of Text, you would pass nonExhaustiveModeMaxMatchCount: 2

TODO

• Verify this is what is desired by Global flag not respected on regex pattern #72
• Add Basic Tests

Out-of-scope

• Rework things to pass a test of nested matchers [b]Bold[/b][i]italic[b]italic and bold[/b][/i] (This may be a bug in the fundamental architecture) -- discuss in Feature: Nested Matchers #81
