Expand description

This encoding allow compression of decimals using integer compression schemes. Decimals can be compressed by narrowing the signed decimal value into the smallest signed value, then integer compression if that is a value ptype, otherwise the decimal can be split into parts. These parts can be individually compressed. This encoding will compress large signed decimals by removing the leading zeroes (after the sign) an i128 decimal could be converted into a [i64, u64] with further narrowing applied to either value.
