This class forms a hash over the IR pulses generated by an
IR remote.
The remote key press is not converted into a code in the manner of
the lirc module. No attempt is made to decode the type of protocol
used by the remote. The hash is likely to be unique for different
keys and different remotes but this is not guaranteed.
This hashing process works for some remotes/protocols but not for
others. The only way to find out if it works for one or more of
your remotes is to try it and see.
EXAMPLE CODE
#!/usr/bin/env python
import time
import pigpio
import ir_hasher
def callback(hash):
print("hash={}".format(hash));
pi = pigpio.pi()
ir = ir_hasher.hasher(pi, 7, callback, 5)
print("ctrl c to exit");
time.sleep(300)
pi.stop()

Initialises an IR remote hasher on a pi's gpio. A gap of timeout milliseconds indicates the end of the remote key press.
