Make companion object accessible from RefinedTypeOps.Mirror

[Iltotore]

Add a ops (or similar name) field to RefinedTypeOps.Mirror to allow access of all constructor methods (apply, option, either...). This is useful when deriving given instances from newtypes.

Example:

Before:

inline given [T](
  using mirror: RefinedTypeOps.Mirror[T],
  constraint: Constraint[mirror.BaseType, mirror.ConstraintType],
  baseEncoder: JsonEncoder[mirror.BaseType]
): JsonEncoder[T] =
  baseEncoder.mapOrFail(value =>
    if constraint.test(value) then Right(value.asInstanceOf[T])
    else Left(constraint.message)
  )

After:

inline given [T](
  using mirror: RefinedTypeOps.Mirror[T],
  constraint: Constraint[mirror.BaseType, mirror.ConstraintType],
  baseEncoder: JsonEncoder[mirror.BaseType]
): JsonEncoder[T] =
  baseEncoder.mapOrFail(mirror.ops.either(_))
