Remove impl<C> $op_trait<PreAlpha<C>> for {f32,f64} impls to work around issue #283

[Ogeon]

The compiler seem to sometimes get stuck in a loop when these operator implementations are involved. This removes them for now, until the issue is fixed.

Closed Issues

• Fixes Compilation error when trying to use palette #283, by removing the problem causing impls.

Breaking Change

Removes the possibility to write 1.0 * my_pre_alpha_value.
