Updates to scanning flow

Out of the box, captur's user experience is balanced for speed and accuracy - built on best practices and what users love.

Users may want something that feels a bit more familiar, or more control over the experience, especially in initial rollouts.

The Captur SDK provides methods to:

1. setDelay() before the scanning starts. The default is 1 second
2. setTimeout() to increase or decrease the time before scanning ends even if no decision has been made. The default is 5 seconds. This is cumulative, so it happens after the delay
3. endAttempt() to return a decision immediately. This can be a solution when the user will not accept the guidance message, and seeks to override AI guidance, or the rare edge cases where the model fails to converge on a decision quickly enough.
