On iOS, each app has its own sandbox which has a temporary directory.
The FileUtil::getSysTempDirectoryPath() method successfully gets this
directory and we create a tiledump directory under it. Sadly, we then
try to write to /tmp regardless of where the temporary directory is.
This commit makes us also write our file in the directory returned by
FileUtil::getSysTempDirectoryPath()

Simplified code:
+ re-use the bit mask as an inner loop counter.
+ turn alpha only rows into zero length with agreed lastPix.
+ keep lastPix around on the stack.
+ handle odd widths in a duplicate slow-path

Also: address parts of #6897, primarily:
* remove the problematic aspect of bumping the last wid in our
TileData, when this could trigger a re-send of a previously
sent delta, causing tile corruption.
* instead append an empty wid entry.
* as an optimization - if the last entry is empty update
the wid - since re-sending an empty delta is of no
concern.
* simplify a number of code-paths that special-case zero length
deltas. All deltas now commence with 'D'.
* still track updates in the JS - by detecting empty deltas.
* shares more code and simplifies various paths.

Store a bitmap of whether a pixel is identical to the last
pixel in a set of four 64bit members. These double as a
simple CRC. Store the allocated row size too, and use the

When creating a delta, the copy command could copy from rows that are
bigger than the height of the tile. This would go unnoticed on light
mode because the js side that applied the delta would apply these out of
bounds rows with a white color, but it is noticable in dark mode. Made
it so the copy command stops copying from out of bounds.

zstd provides for much faster compression server-side, as well
as better decompression.
zstd allows us to de-compress a keyframe and several deltas in a
single call in JS, so it is necessar to add a terminator to the
delta stream so that we can detect when to flush the buffer we
are working on - so the next delta applies to the correct data.

Squashed from feature/deltas-expanded.
TileCache changes:
+ add montonic sequence (wid) numbers to TileData
+ account for sizes of TileData with multiple blobs
+ simplify saving and notifying of tiles
Sends updates (via appendChanges) based on the sequence the
right mix of keyframes and/or deltas required as a single
message, and parse and apply those on the JS side.
We continue to use PNG for slide previews and dialogs,
but remove PngCache - used by document tiles only.
Annotates delta: properly as a binary package for the websocket.
Distinguishes between deltas and keyframes we get from
the Kit based on an initial un-compressed prefix
character which we then discard.
kit can be forced to render a keyframe by oldWid=0
Track invalidity on tiles themselves - to keep the keyframe around.
We need to be able to track that a tile is invalid, and so subscribe
to the updated version as/when it is ready - but we also want to
store the keyframe underneath any deltas.
force rendering of a keyframe for an empty slot in the TileCache.
force tile sequence to be zero for combinedtiles - so the client can
always request standalone tiles with explicit combinedtiles, or tile
requests.
move Blob to Common.hpp
use zero size for un-changed tiles.
remove obsolete render-id, and color deltas in debug mode.
cleanup unit tests for non-png tile results.
