Encoding error on Pico-8 glyphs (or possibly: AttributeError: 'bytes' object has no attribute 'hex')

Dear dddaaannn.

I am trying to use your picotool to minify my game. Currently I have:
65302/65536 char count and 8136/8192 token count.
When I am trying to use luamin on my cart I get:

		
```
C:\Python34>python p8tool luamin saveyourself.p8
saveyourself.p8 -> saveyourself_fmt.p8
warning: token count 29022 exceeds the Pico-8 limit of 32768Traceback (most rece

    yield bytes(newdata).hex() + '\n'
AttributeError: 'bytes' object has no attribute 'hex'
```

I have ton of text packed into loooong strings if that helps.
Please help me, as I can't even export my game to html at this point.

Thanks in advance!
