Constance Beguier 4c3c00bced Optimized short range check on 4 and 5 bits (#21) 
Short range checks on 4 and 5 bits are now performed with only one lookup (instead of 2).
To do that, we added a column `table_short_range_tag` in the lookup table.
This new column `table_short_range_tag` contains the value
- 4 for rows used in short range check on 4 bits
- 5 for rows used in short range check on 5 bits
- 0 for rows used in short range check on 10 bits

Jack Grigg 9a12beee73 halo2_gadgets: Rename `halo2` to `halo2_proofs`

to keep the commit size down. This commit performs the rename in a
single pass.

- The crate module structure from `orchard` has been flattened.
- The book pages we want to include in `halo2` have been moved to their
  target location, to avoid any conflicts during the merge.
- Common files that already exist in zcash/halo2 have been removed.
