Description

1. Implement 'extract_bits' with Arm64 GoLang Assembly. '_pext_u64' is the x86 bmi intrinsics for extract_bits.
There is no equivalent of '_pext_u64' instruction on Arm64.
The task is to implement equivalent of '_pext_u64' by Arm64 assembly.

2. Implement 'levels_to_bitmap' with Arm64 GoLang Assembly for greaterThanBitmapNEON
