If you chain PCA9685s, creating multiple instances of a pwm object results in buggy behavior (eg with two chained banks, bank #2 gets distorted PWM values, bank #1 doesn't work at all). Not sure if this is as intended, but thought it worthwhile to mention.

Can you tell me more about this setup? Do you have any test code that you could share?

I reproduced the problem today and I believe I have found the issue and a fix. Expect an update soon after some more testing.

Fixed in main branch. Objects that should not have been reused were. Oops. Tested with two PCA9685, one at address 0x40 and one at 0x41.
