A payload was conceptually a value with an ID. That has been formalized by removing the ID from the payload and having separate FValue and FValueId types. This separation cleans up the API in a few areas, and provides a more natural path to providing a basic key/value API.

Use GetValue().GetData().Decompress() in place of GetValue(), or the equivalent for GetAttachment(Id). The removed accessors kept a cache of the decompressed payload and required synchronization to be safe to call from multiple threads.

- Implemented only for the structured cache initially.
- Records are stored as compact binary packages with payloads stored within the record if small enough.
- Records are stored in Records/{Bucket}/{01}/{23}/{456789abcdef0123456789abcdef01234567} based on the hash in the cache key.
- Content that exceeds the size allowed for storage within the record is stored in Content/{01}/{23}/{456789abcdef0123456789abcdef01234567} based on the hash of the content.
- Both records and content are written to disk with their hash as a suffix, and are always checked on load.
- Maximum size of compressed data stored in the package can be configured by MaxRecordSizeKB and MaxValueSizeKB.
- Maintenance of the cache, to delete unused files, has been rewritten and can now scan ~175k files/second on modern hardware, though is limited to 10k files/second in the config to avoid adding too much overhead.

Any function that may create a request now has a IRequestOwner& parameter, and uses the Begin and End functions on the owner to manage the lifetime of any requests that it creates, as well as using End to invoke the completion callback for any request which has one.
The new FRequestBarrier may be used to block a group from being considered complete in a scope where more requests may be added to it.
