v0.2.0

• Added a type mismatch when converting from a float -> int if the float is not a whole number.
• Added a CompareOpts type. This can be used to control how type names are reported for mismatches, as well as determining if two types are convertible.
• Added a TypeNameSimple func, which returns type names without the bit size (for int, uint, and float types). This is used with CompareOpts.
