Update css_analyzer.py - add float()

[Jonius7]

RGBA needs an extra float() conversion on line 73 of css_analyzer.py.

RGBA format does not support float types. Its a 4 byte data type where each byte, containing 8 bits, can represent 0-255 (2^8-1). I'm not quite following the reasoning here.

[Jonius7]

The a value is a float between 0 - 1

If you try to use a rgba color value eg: with 0.5 as the a value you get this error:

You use float() on line 81 as well
That being said, line 71 also needs to be changed since it is converting raw RGBA

Ah okay I see, thanks. CSS apparently uses an unconventional RGBA format. They represent the alpha byte as float!

[shdwmtr]

For clarification, what does your color config file look like? Millennium doesn't support customizing alpha values, it was a limitation with and I never got around to adding a better color picker.

[Jonius7]

I did take out the rbga value and used color-mix in my CSS instead

But the value I had was something like

--mycolor: 53, 56, 79, 0.5

I might not merge this for now then if its a non-issue, I don't want to break anything. I'll keep this open though; if I ever add alpha support I'll add it to this PR.
