Move the ALP algorithm description (everything from the Overview section onward) out of Encodings.md into a new AlpEncoding.md, keeping the introductory description and a link in Encodings.md. The content is moved verbatim; the only edit is updating the RLE/Bit-Packing Hybrid link to point back to Encodings.md. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Rationale for this change
As suggested by @pitrou in #557 (comment), the ALP algorithm description is long enough that it deserves its own file, following the pattern of other detailed specifications.
