Fix SNES_LATCH_FILTER typos and missing content

This commit fixes some issues related to SNES_LATCH_FILTER in the spec,
which includes adding it to the "Assigned Packet Keys Without
Descriptions" section, fixing the key

This commit also fixes some incorrect data in the CHANGELOG for the
2023-09-24 commit list of changes.

To prevent any of the packet diagrams from aligning incorrectly, all
tabs in the spec xml file have been replaced by 2 spaces.

The previous commit summary had errors in it.  It should have stated:

Changed
- Specify INPUT_CHUNK offset for Index Value of TRANSITION packet

Fixed
- EXPERIMENTAL packet drawing error and packet value length

Added
- PORT_OVERREAD packet
- SNES_LATCH_FILTER packet
- Port value to TRANSITION packet
