Optimize Writer.writeLeb128
Rewrite `writeLeb128` to no longer use `writeMultipleOf7Leb128` and instead:
* Make use of byte aligned ints
* Special case small numbers (fitting inside 7 bits)
Amongst u8, u16, u32 and u64 performance gains are between ~1.5x and ~2x
Amongst i8, i16, i32 ane i64 perfromance gains are between ~2x and >4x
Additinally add test coverage for written encodings
