add analog 8ch mux/demux

[LHSmicius]

As always bot will fail because base part doesn't have description.
I'm not sure about multiplexer's I/O naming. I made base part according Nexperia datasheet where channels named Y0, Y1,..., Y7, and output (let's call it so) named Z. On internet I found many examples with different namings. Our logic components (AND, OR, XOR.....) already in pool uses letters A, B, C, .... for channels and 'Y' for output. Maybe I should continue that way.... Every manufacturer uses their own naming for multiplexer's I/Os...

The dual power is a bit funky, @carrotIndustries any ideas?

Bot!
I don't like that every manufacturer uses different pin names for such a basic device as multiplexer, so I thought it would be nice to have same naming in all logic components in the pool, but maybe I am wrong.... Maybe it should be according to datasheet... The part would look like here.

My point is - we could use same base part for many mux/demux parts, but all manufacturers uses their proprietary pin names in datasheets:
