Additional Can Protocols, including Io Expansion

[xtitoris]

Implemented additional CAN protocols

AFR:

• Haltech W2B
• EcuMaster L2C
• Emtron ELC
• Link Lambda2Can
• Motec LTC

EGT:

• AEMNet 2224
• Haltech TCA
• EcuMaster Classic
• EcuMaster Black
• Emtron ETC4
• Link TCCXX
• Motec E888

IO Expanders:

• Haltech IO12 (sending and receiving)
• EcuMaster SwitchBoard (sending and receiving)
• Motec E888 (only sending, could not find enough info on received dataframes)
• Emtron EIC16M (only sending, does not have any outputs)
• Microsquirt IoBox (sending and receiving, based on @dron0gus branch)

Added canbus speed selection for f1_dual_rev1, as several protocols need 1Mbps
Updated ini file to allow configuring all of that
Created dbc files for all of the protocols
Bench-tested with synthetic messages for sending and receiving data

@dron0gus: I think here it would be a bit easier to review, as it is already synced with main rusefi branch.
@rusefillc, @mck1117: Any additional comments are welcome

it is not feasible to review a +4171 -425 PR in one shot

@xtitoris this is very impressive but :(

But unfortunately things are somewhere between unhealthy and worse - see https://github.com/mck1117/wideband/pulls

https://github.com/rusefi/wideband/tree/2026-02-22-io-expander-support-backup backup just in case

A smaller independent effort could be adjustable CAN bad rate

magic uint8_t mode is scary/fragile, I would rather that be an enum class

But again, I have no idea how any of this could move forward in light of all the above mentioned drama

const CANConfig& GetCanConfig(uint8_t mode) {
    mode &= 0x03;
    switch (mode) {
        case 0:

Ah, yes, forgot to clean this up.

Yes, but it is possible to give it a cursory glance, and discuss things, like how to best split it up into more feasible chunks, or any other thoughts on the matter.
