We added the "cBTC" denomination but forgot to test it.
Add units test for "cBTC" as we do for the other denominations. Put all
the tests lines of code in the same order as the enum variants so a
reader can see easily that all cases are tested.
We have multiple constructors for `Amount`, one of which accepts an
integer representing whole bitcoin.
In an attempt to make the API crystal clear change the parameter type
used for whole bitcoin to either `Into<u64>` or `u32` instead of a
`u64` which may well be mapped to sats in the mind of developers (it
is in mine anyway).
To prevent rounding errors converting to and from f64 change
`SignedAmount` `MAX` and `MIN` to +/- `MAX_MONEY` which are within the
limit in f64 that has issues.
Add checks to `from_str_in`, `checked_add`, `checked_sub` and
`checked_mul` that the result is within MIN and MAX.
Modify tests to work with new `MIN` and `MAX`

To prevent rounding errors converting to and from f64 change
`Amount::MAX` to `MAX_MONEY` which is below the limit in f64 that has
issues.
Add checks to `from_str_in`, `checked_add` and `checked_mul` that the
result is below MAX, where previously a u64 overflow was relied on.
Change tests to account for new lower MAX that is within the range of
SignedAmount and does not overflow so easily
Remove overflow tests
`Amount::MAX` is now below `u64::MAX` and within the range of values for
`SignedAmount`. These tests therefore do not overflow.
In effective_value there is no error with `Amount::MAX` and the correct
value is returned.
In psbt the removed test is effectively the same as the previous test.
Modify `Amount` tests to work with new `MAX`
Tests need to be changed that checked values above the new `MAX` or
`Amount::MAX` was out of range for `SignedAmount` which it isn't anymore
Sometimes JSON parsers may munge floats. Instead of using `f64` we can
serialize BTC amounts as strings.
Includes addition of `alloc` feature gate to `DisplayFullError` to
remove lint warnings when building with `--no-default-features`.

Close the two pubic enum error types in `units::amounts`. All the other structs are closed already because they either have private fields or marked `non_exhaustive`.

Close the two pubic enum error types in `units::amounts`. All the other
structs are closed already because they either have private fields or
marked `non_exhaustive`.
Add/update the from_int group of functions to provide one that errors
and one that is const and panics (errors in const context are not useful
because one cannot call `unwrap` in const context).
