Add disabled channels filter

[diaza]

Filters out disabled channels.
The input file is a json dictionary where the keys are strings '<io_group>-<io_channel>-<chip_id>' and the values are lists of the channel_ids. The file format can be updated in the future.
The list of disabled channels has been added as an additional datatype in 'geometry_info', and the filtering is done in the event building stage (in the same line where parity == 0 is enforced).

Thanks Alex! Two things that we need to take into account still:

1. The disabled channel list is extracted from the 2x2 config files, which means that io_channel will not always be the same for the chips in the simulation file. One way around it is to convert io_channel both in the disabled channel list and the packet file to tile_id using: tile_id = (io_channel - 1) // 4 + 1, and this way you can locatethe chip/channel on a tile independently from the hydra network.
2. The disabled channel list does not include fully disabled ASICs. I will provide that as well, but a similar question regarding the io_channel of disabled chips comes to mind. So I will probably wait for a proposed solution to the issue above before I make a file accordingly.
