lua CAN relay performance

[rusefillc]

scripts at https://github.com/rusefi/rusefi_documentation/tree/master/OEM-Docs/VAG/2006-Passat-B6/HOWTO

actual traces with different editions of scripts https://github.com/rusefi/rusefi_documentation/tree/master/OEM-Docs/VAG/2006-Passat-B6/2024.02

I am trying to execute lua at 100Hz in order to send MOTOR_1 640/0x280 at 100hz
traces show that MOTOR_1 is only send out at ~12hz

now comes a red flag
for one "onTick" invocation we consume 100 RX packets and we spend roughly 0.5ms per packet

• would be nice to reproduce something without real passat
• open question if we shall go with build-in profiling https://github.com/rusefi/rusefi/wiki/Developer-Performance-Tracing
• open question if TX needs queuing
