psbt: modify Extract method to return the transaction directly 
In this commit, we modify the Extract method to return the transaction
directly as in many cases a user will likely want to write the
transaction to disk, or perform additional validation rather than obtain
the raw bytes directly.

psbt: remove Creator struct, create New function as entry point into package 
The creator struct really didn't do anything before, as a result in this
commit we move to get rid of it, and create a `New` method as
customarily used in go packages.

9e5f4b9a99 gcs/gcs: use sort.Slice instead of sort.Sort, remove uint64Slice 
This commit removes the uint64Slice type and performs sorting during
filter construction and ZipMatchAny using sort.Slice. The benchmarks
indicated that this speeds up BuildGCSFilter and ZipMatchAny by 10-12%,
likely to the overhead of needing to resolve the sort.Interface methods.

The benchmarks indicate that this improvement is not present for the
smallest query size in our benchmarks, i.e. 100 elements, but the
reduction is only about 3%. This would indicate the at these small
values, the use of reflection is actually slightly slower than interface
method resolution in total.

gcs/builder: remove the AddScript method as it's no longer used (#121) 
In this commit, we remoec the AddScript method as it's no longer used,
and AddEntry should be used in place for adding pkScripts to the
filters.

0ecd90b8d6 gcs: update fp and modulus values based on recent optimality analysis 
In this commit, we decrease the default fp rate to 19, or 1/2^19. We do
this as recent analysis by sipa on the bitcoin dev mailing list has
shown that optimally, we can use a value of 2^19 for the fp rate, while
use n=1.497137*2^P rather than n directly. As a result, we can shrink
the filter size by quite a bit, while still maintaining a sane false
positive value.

hdkeychain: update test case error string due to btcec changes 
A bug was recently fixed in btcec wherein we would fail to detect
invalid point decompressions for the curve. This how now been fixed, and
as a result, we'll fail an invalid point earlier in the ParsePubKey
method. We update the error string to reflect this change.

e87fef40f3 gcs: ensure benchmarks aren't optimized away by the compiler 
This commit modifies the benchmarks a bit to ensure that the
computations themselves aren’t optimized away. We do this by binding
each variable to a local variable, and them ultimately a variable at
the package level scope.
