Convert more catalog formats

torchfits convert catalog.fits out.parquet --to parquet --hdu 1
torchfits convert catalog.fits out.csv --to csv --hdu 1
torchfits convert catalog.fits out.tsv --to tsv --hdu 1
torchfits convert catalog.fits out.arrow --to arrow --hdu 1

Notebooks

Lean _repr_html_ previews on TensorHDU, TableHDU, and TableHDURef.

Performance

Scorecard refresh: CUDA 0 strict deficits; Linux CPU 1; Mac MPS 16. Methodology: Benchmarks.
