pillar1989 34c1d6ff91 fix: use pSPI->begin() and add skipSpiBegin option for ESP32 compatibility 
ESP32 users need to call SPI.begin() with custom pin assignments before
using the library (GPIO matrix). The hardcoded SPI.begin() in
mcp2518fd::begin() overwrites this configuration.

Changes:
- Replace SPI.begin() with pSPI->begin() (consistent with MCP2515)
- Add optional _initSPI parameter (default true) to begin() across
  MCP_CAN, mcp2515, and mcp2518fd so ESP32 users can skip SPI init

Existing code is unaffected — default behavior unchanged.

Closes #158
