Description
The Adafruit MPC23017 library is not compatible with Teensy4.
I want to use an MPC23017 on the Wire1 port of Teensy4.1.
The library only works with Wire0. How can I set the MPC23017 on Wire1?
The I2C speed cannot be set to 400 kHz!

Research direction
No source file or test is named in the issue. Start by locating how the library selects its I2C Wire instance and configures bus speed, then reproduce the setup on a Teensy 4.1 using Wire1. Done means the MPC23017 can use Wire1 and the I2C speed can be set to 400 kHz.
