Module runtime

Runtime Pattern implementation which is optimized for zero-allocation deserialization and high-performance runtime use in DateTimeFormatter.

This module is meant to remain an implementation detail and can evolve to utilize all runtime performance optimizations ICU4X needs.

For all spec compliant behaviors see reference::Pattern equivalent.

🚧 This code is considered unstable; it may change at any time, in breaking or non-breaking ways, including in SemVer minor releases. While the serde representation of data structs is guaranteed to be stable, their Rust representation might not be. Use with caution.
