Using Custom spike generation processes in Lava-DL as input

[JDRanpariya]

Dear Team

I have a custom process called SpikeGenerator and I have implemented two ProcessModels for it which differs in ClassName and implementation of run_spk method.

1. I would like to know how can I choose between those ProcessModels in my code based on either ClassName or tag.

2. In lava-nc I can use spike__gen.s_out and pass it to first layer, but how can I use the spiketrain generated data in a lava-dl Network, where I plan to use it as input? Do I have to make it work with torch data loader? what's the recommended way to use generated spikes data into Lava-dl Network?
