BIP341: Fix definition of NUMS point

Improve BIP-341 wording 
Reading the spec closely the different language used for serialization of input outpoints and input amounts was
confusing on first read. This change uses the same language
for both, which makes it easier to read.

BIP 341: allow taproot_sign_key with no script tree 
In contrast to taproot_output_script, taproot_sign_key was not able to deal with
a script_tree that is None. This commit fixes taproot_sign_key such that it can
sign for such outputs.

This commit avoids changing the behavior of the functions except
taproot_sign_key at the cost of having some code duplication. Alternatively, one
could let taproot_tree_helper deal with a None script_tree directly.

BIP 341: Fix taproot_tweak_pubkey 
`lift_x` returns `None` if the input integer is not an X coordinate on the curve
to indicate failure. `point_add`, on the other hand, interprets `None` as the
point at infinity. Therefore, without this commit, if the internal `pubkey` is
not a valid X coordinate, the function will not fail, which contradicts the
specification in the "Script validation rules section". Instead, it sets `Q` to
`t*G`.

Convert seckey0 to bytes at the start of the function.
Return the output as bytes for consistency with the rest of the code.

BIP-341: allow future softforks for leaf version signature verification 
Currently the BIP-341 and BIP-342 leave the question of how to verify signature for non-`0xC0` leaf version scripts undefined. I haven't checked the Bitcoin Core code for that matter yet, but (1) I think we need to cover signature validation of non-`0xC0` leaf version scripts in this standard and (2) the only way of doing that is "always succeed" rule for the future leaf version values (otherwise we will need a hard fork to introduce them).
