Merge rust-bitcoin/rust-bitcoin#2436: Add unchecked variants to Amount and SignedAmount 
df1d2f6eb5 Add unchecked variants to Amount and SignedAmount (yancy)

Pull request description:

  The checked variants have worse performance than the unchecked variants due to the additional branching operations.  To improve performance where overflow is either not possible or not a concern, unchecked variants of `Amount` and `SignedAmount` are introduced for addition, subtraction and multiplication.

  Note, it seems the default behavior for the test framework is to panic on overflow, so I haven't figured out a good way to add tests for this.  Marking as a draft for now.

    ACK df1d2f6eb5 gonna go ahead and merge this, we can revisit if necessary when we look at `units` overflow behavior in general
