@KevinH: Does bk.addfile() support bytearrays?

I did a quick test and came up with the following proof-of-concept code, which will add a blackletter ttf font located in the plugin's directory to the epub:

#!/usr/bin/env python
import os, inspect, uuid

def run(bk):
    basename = 'WallauRundgotisch-Heavy.ttf'
    binary_path = os.path.join(os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe()))), basename)
    file_handle = open(binary_path, 'rb')
    uniqueid = 'id' + str(uuid.uuid4())[24:82]
    data = bytearray(file_handle.read())
    file_handle.close()
    mime = 'application/x-font-ttf'
    bk.addfile(uniqueid, basename, data, mime)
    
    return 0

def main():
    print('I reached main when I should not have\n')
    return -1

if __name__ == "__main__":
    sys.exit(main())

This code appears to be working, but I'm wondering if there is a better and/or more desirable method to add binary files?
