Proposal for Compact Decimal Types

[younies]

Description

Instead of having a single compact implementation that uses SignedFixedDecimal, we propose introducing two separate types:

• UnsignedCompactDecimal
• SignedCompactDecimal

Benefits

• Type Safety: Clearly distinguishing between signed and unsigned types can help prevent runtime errors.

How do you envision the nesting?

Should it be:

1. Compact<Signed<Decimal>>
2. Signed<Compact<Decimal>>

Triage: remains in 2.2 as long as compact decimal is a headline item
