feat: profile jumpnbump, kronos, lowresnx, lutro, m2000

Browse Source 
add core_classification and upstream to all five profiles. kronos:
add ROM cartridge files (mpr-18811-mx.ic1, mpr-19367-mx.ic1), add
archive: field to STV blobs, remove unverified MD5 hashes, fix
cores list (remove yabause_libretro). jumpnbump: fix incorrect
note about embedded data. lowresnx, lutro, m2000: add missing
classification fields.

notes: |
Kronos is a Sega Saturn and ST-V arcade emulator forked from Yabause.
The libretro repo at libretro/yabause ships the older "Yabause" core
(yabause_libretro) which handles Saturn only and has no STV support.
Kronos is a Sega Saturn and ST-V arcade emulator by FCare, forked from
Yabause. Requires OpenGL 4.3 compute shaders.
Saturn BIOS search order (Kronos):
Saturn BIOS search order:
1. {system}/kronos/saturn_bios.bin
2. {system}/saturn_bios.bin
3. {system}/sega_101.bin
4. {system}/mpr-17933.bin
First file found wins. Real BIOS required, HLE is deprecated and causes
issues. Multi-disc (m3u) also forces real BIOS.
First file found wins. Real BIOS required (HLE deprecated, only available
via kronos_force_hle_bios core option for debugging).
Saturn BIOS search order (YabaSanshiro / Yabause):
1. {system}/saturn_bios.bin
2. {system}/sega_101.bin
3. {system}/mpr-17933.bin
Falls back to HLE if none found, but HLE is not recommended.
ST-V BIOS: {system}/kronos/stvbios.zip or {system}/stvbios.zip
MAME-style ZIP containing region-specific EPROMs. Kronos picks the best
match by game region and kronos_stv_favorite_region core option (EU/US/JP/TW).
ST-V BIOS (Kronos only):
{system}/kronos/stvbios.zip or {system}/stvbios.zip
The ZIP is a MAME-style romset containing region-specific EPROMs.
Kronos picks the first matching BIOS by region, with a configurable
"favorite region" core option (EU/US/JP/TW). The ZIP must contain
at least one of the BIOS blobs listed below. ST-V games are detected
automatically when loading a .zip file.
ROM cartridges for KOF95 and Ultraman are auto-detected via game database
(db.c) and loaded from system_dir when the corresponding game is running.
BIOS loading: libretro.c retro_load_game() lines 1601-1727.
