* Implement best block hash correctly
* Handle no common history
* Fix getBlockProof to be BigInt instead of UInt32
* Fix warnings
* Make get best filter use chainwork
* Remove unused function, test isMissingChainWork
* Fix comparisons for chain work in sql
* Fix migrations from rebase
* Fix CI error
* Fix postgresql
* Made the standard non-interactive tx finalizer simple using composition of its (reusable) pieces
* Responded to code review and made minor improvements
* Fixed docs
* Add more optimizations, MultSignatureScriptPubKey.isMultiSignatureScriptPubKey() fails fast if it's not a valid multisig spk, also use more caching inside of Number's (UInt64, UInt32, etc)
* Fix shortChannelidTest
* Cache popular UInt64 numbers that are used in ScriptPubKey's. This reduces allocations which reduces memory usage
* Attempt to optimize block tests more to avoid timeouts
* Fix asm.tail bug
* Make parseRedeemScript just return a ScriptPubKey rather than a Try[ScriptPubKey]
* Make encoding a UInt64 to hex more efficient
* Cache Transaction.bytesSize so we don't need to serialize everything again to estimate the byteSize
* Refactor CryptoBytesUtil.addPadding() and it's usage in UInt64
* Use StringBuilder.append() rather than StringBuilder.addAll() which is not supported in scala 2.11 & 2.12
* Address nadav's code review
* Implemented parseDERLax signature parsing and bumped bouncy castle version to most recent
* implemented using iterators
* Factored out common functionality and added comments, it is readable now! Deleted C-like version in place of this one after property based tests showed them to be equivalent
* Made compatible with scala 2.12
* Make compatible with scala 2.11
* Added tests for lax DER signatures
* Refactored Transaction
Created RawTxBuilder
Created RawTxFinalizer as layer on top of RawTxBuilder
Introduced RawTxSigner and replaced TxBuilder!
Deleted TxBuilder!
* fixed things after rebase
* Made RawTxBuilder compatible with older versions of scala
* Began responding to review
* Made Finalizer take a Builder rather than the other way around
* Added composition for finalizers
* Ran scalafmt
* Updated txbuilder example documentation
* Moved tests from old TxBuilderTest files to relevant new test files
* Added scaladocs
* Reduce number of property based tests on BIP32PathTest and add a Future to NetworkPayloadTest's property based tests so it hopefully runs faster on CI
* Run scalafmt
* Make a few more property based tests async
* Make forAllParallel, refactor some test cases to use it
* Make BlockMessageTest async
* Bump timeout
