[load_lazy] expand options.load_lazy to work for the loading of multiple files

[anjakefala]

Currently, options.load_lazy being set to False, results in the loading of all subsheets for embedded sheet formats like xlsx or hdf5. It would be great if it would also load all files users seperately pass to VisiData.

e.g. vd sample.tsv benchmarks.csv with options.load_lazy set to False should mean both sample.tsv and benchmarks.csv are loaded upon start-up.

It would be great if you could also explicitly set this on a sheet itself. I have some sheets which are part of an indexSheet that are processor intensive and so want these loaded only on user interaction

I briefly tried MySheet.class_options.lazy_load = True and it didn't seem to work

That should work, @geekscrapy ! Maybe try with load_lazy (I made the same mistake myself :)

Hmm doesn't seem to work for my sheets in the index sheet, and it doesn't look like it should:

It should have worked if you set it on the index sheet. Did you fix the mispelling of the option when you set it? (from lazy_load to load_lazy)

I have tested MySheet.class_options.load_lazy = True and it does work!
