Library folders can now carry what the library knows about them beyond
their photos: FolderRecord (for now a colour label), kept in
Catalog.folder_records under the folder's identity (folder_key) and
changed through Op::SetFolderRecord, one undo step. An empty record is
never kept; a path that names no folder is refused.
folder_records_follow builds the ops that carry a folder's records and
those of its subfolders to its new place on rename or move (dropping
stale records left at the destination), so they can be committed with
the photos' relinks. FolderNode reports the label.

Keywords existed only as `a|b|c` strings on photos: one couldn't be
created before a photo had it, nor a parent made to organize under.
The catalog now has a keyword list (`Op::SetKeyword`, format version
4): a keyword listed on its own is in the tree with no photos, its
parents too, and carries Lightroom Classic's keyword tag options
(`KeywordInfo`: synonyms, include on export, export containing
keywords, export synonyms, person), exported by default. Undo restores
what was listed, as it was written. Version 3 libraries open and are
rewritten as 4.

A catalog written before the lens data was read at import (RW2/RWL from
v0.4.0) has none stored, and the lens correction stays off. Reload now
stores the fresh probe's lens data (new journaled, undoable
Op::SetEmbeddedLens; catalog format 4) and, for photos still at import
settings, switches the correction on as import does. Edited photos and
photos with a default-preset look keep their settings.
Album.order and Op::SetAlbumOrder; album_children lists folders first, then
by place, then by name. Moving an album drops its place and undo restores it.

main added Op::SetBrowsed, Catalog.browsed and Photo.local_baseline while
the snapshot still said version 1, so v0.2.0 read such a library in part
(unknown ops as log damage, unknown fields dropped on its next snapshot).
- journal::VERSION = 2 (now public), with a format table and rules in the
journal docs; a test with an exhaustive match over Op makes adding a
variant fail until it is assigned a version.
- Journal::open reads the snapshot header first and refuses a newer
version with CatalogError::Newer ("written by a newer version of
LightCraft"), even when its catalog wouldn't parse.
- A log record whose CRC matches but whose op doesn't parse is "newer",
not damage or a torn tail: refused before any file is modified.
- Opening an older (or snapshot-less) library writes a snapshot in this
format before anything is appended (LoadReport::upgraded_from); a new
library gets one at once, so v0.2.0 refuses it instead of reading a bare
log.
