Create FixedIncrements constraint

[amontanez24]

Problem Description

As a user, it would be useful to have a constraint that specifies the lowest common increment the data can appear in. For example, if my data must be a multiple of 5 or 7, it would be useful to be able to specify this.

Expected behavior

• Remove the Rounding constraint. This functionality should be handled by the HyperTransformer
• Add a FixedIncrements constraint
  • Init params should be:
    • column_name: String that is the name of the column to be constrained
    • increment_value: Int that is the value to make sure all data should be divisible by. Must be greater than 0.
  • Validation
    • If the increment_value is less than 0 or 0, we should raise an error during initialization.
    • If the data is not evenly divisible by the increment_value then that row is invalid
    • Nans should be ignored during validation
  • reverse_transform
    • Round synthesized values to nearest multiple of increment_value

Additional context

• one option for transform is to divide all values by increment_value. Then on reverse you can round to the nearest int and just multiply.
