Integer Channel numeration in LinSpaceBuilder makes awg assignment difficult

[Nomos11]

Translating the ChannelIDs to integers in the LinSpaceBuilder makes it difficult to spread the program to multiple AWGs. In the current master branch, using multiple AWGs for a LinSpace program is not possible.

I feel like this could be solved by either adding metadata to the program, or have the channels be ChannelIDs still.

This can also get rid of having to supply the channels into the linspacebuilder when building the program

The idea is to use a builder for each AWG. This also leads to easier programs for the awg

channel_sets = [('HDAWG_1_A', ), ("HDAWG_2_C", "HDAWG_2_D")]
for channel_set, awg in zip(channel_sets, awgs):
    awg_program = pt.create_program(channel_set, builder=awg.get_builder(), ...)
    awg.upload(program_name, awg_program, ...)

will that idea be relevant for 1.0?
otherwise, for readability it may still be worthwile considering to have ChannelIDs as identifiers, or what would be the drawback?
(it may be favorable fofr the awg driver afterwards)

The drawback is that you have to use dictionaries everywhere which makes the code more complex, iteration orders path dependent and the structures unhashable. Although we can use frozendict which is already a dependency anyways.

(for the actual translation to the awg program so far i only needed the final commands to be hashable, which would still be given with ChannelIDs I think)
are hashable structures needed elsewhere so far? most dataclasses don't seem frozen
