Implement the Float Module of the Morphir SDK

Is your feature request related to a problem? Please describe.
Morphir's SDK seeks to have parity with much of elm/core and should have full parity with elm/core Result.

Describe the solution you'd like
Implement the functions in [elm/core Float](https://github.com/finos/morphir-elm/blob/main/src/Morphir/SDK/Float.elm) and add tests. Over time we will add more functionality here, but this is a good start.

Describe alternatives you've considered
N/A

Additional context
N/A

Start by comparing the linked elm/core Float.elm implementation with the Morphir SDK's corresponding Float module, then identify the local test location for SDK modules. Implement the requested Float functions and add tests covering them; done means the selected functionality matches the elm/core behavior and the tests pass.
