fix high cpu load problem + apply flake8 rules + fix is syntax

[devprofile98]

1 - using pass in while when checking for ready on line 115 causes high CPU load, something around 100% CPU use, a small sleep will release CPU clocks for good use. 2 - use of is for comparing two number in python is wrong and == should be replaced. 3 - flake8 rules applied to make python code more readable and clean

Hi! Thanks for the PR. I'll check it out by the end of the week. I'll also submit a whole new version based on interrupts instead of a loop that waits, in order to avoid freezing the CPU while waiting for the data line to go LOW, so I'll pull this into the new version as well.
