rABC1c69a840da62: [electrum] don't use ecdsa for basic bytes <-> int conversion

There are python builtin methods for that.

It is also a good opportunity to remove the misleading Python 2 era _to_string terminology when the output is actually bytes.

do you think it makes sense to keep this 32 as a defined constant somewhere, e.g. PRIVATE_KEY_BYTECOUNT ?

repeated 4 times in this diff, isn't (widely) intuitive why this should be 32.

You're right, that would improve things quite a bit.

replace the magic 32 number with a constant
