Doesn't support multiple I2C ports

[goodmanj]

The TMAG5273 class includes an _i2cPort field that gets initialized by the begin() method, so it should allow you to talk to TMAG sensors on multiple I2C ports on microcontrollers that support that. But the implementation of readRegisters() and writeRegisters() explicitly use the Wire object, so they can't be used for Wire1 etc.

I tried forking the repo to fix this myself but ran into technical difficulties, not sure why.

Thanks for the hint, i was missing that.

You can easily fix it by replacing all "Wire." (with the dot) by "_i2cPort->" (with the arrow)
you need to change the dot to the arrow since i2cPort is a Pointer.

BTW its dangoerous to use TMAG5273_I2C_ADDRESS_INITIAL since according to the datasheet it depends on the exact Chip version, there are 4 possible initial i2c addresses:

see: Table 6-2 on page 16 of the datasheet:
https://www.ti.com/lit/ds/symlink/tmag5273.pdf

("read adress" and "write adress" can be ignored, its just the leftshifted i2c Address, once with 1 as LSB, once with a 0)
