28f67764ec bip-taproot: clarify bip-schnorr reference code 
- update the paragraph in question to more clearly convey that the helper
  functions, and not the Python3 example code, are from the bip-schnorr
  reference code

- add a link to the reference code in
  https://github.com/sipa/bips/blob/bip-schnorr/bip-schnorr/reference.py

758be14a2b remind reader where [:] is defined 
in addition to `point`. This caused confusion for one reader who expected inclusive at end of range.

3d97967b97 fix: script spend, not key spend 
For the key spend the script tree depth is not revealed, it is only done for script spends. This sentence makes sense only for the script spend.

d87c5c8801 use bytes() instead of b'' - avoid markdown issue 
Currently github markdown renders `b''` inside `<source>` tags incorrectly. This makes `h = b''` show as `h = b` and creates some confusion.
The issue can be avoided by using bytes() to create empty byte array
