L2cache data

[emilkind]

Thanks for the L2 support that came with #151 . I was wondering if it is possible to add support for querying the L2 cache. I would like to get the L2 volumes. Maybe something a long the lines of this:

seg_id = "720575940625434249" # exp_id
l2ids = flywire_l2ids(seg_id)
l2ids = flywire_ids(l2ids, integer64 = FALSE)
fcc = flywire_cave_client()
l2data = reticulate::py_call(fcc$l2cache$get_l2data, l2ids)

Thanks. Good idea. I have some WIP code along these lines. Will try to merge soon.
