add range task

[SamuelJanas]

Added a RangeTask.

This task filters notes_df that starts between start_sec and end_sec.

I'm not entirely sure as to the use of two <PARAMETER_x> tokens. I was thinking about some other approaches:

• <PARAMETER_x_y> for range in one token.
• enclose notes tokens in <RANGE_START> <RANGE_END>. This would be easier to combine with other tasks. to potentially create top_line_in_range task without explicitly defining it.
• <PARAMETER_x> but pre-determine the end after start + ~5 seconds. The x would signal the start time.

Given results of the experiments so far, I'd say that 5 and 10s interval are way too long. We can still include them, but I'd look for a way to have this type of task mask 1-5s of music with many possible starting points. I think this could either be achieved by a pretty large config with many combinations, or another approach to integration with the "PianoDataset" we use for training 🤔

I'll give it a look and see what works.
