This patch adds support for IES files, a file format that is commonly used to store the directional intensity distribution of light sources.
The new IES node is supposed to be plugged into the Strength input of the Emission node of the lamp.
Since people generating IES files do not really seem to care about the standard, the parser is flexible enough to accept all test files I have tried.
Some common weirdnesses are distributing values over multiple lines that should go into one line, using commas instead of spaces as delimiters and adding various useless stuff at the end of the file.
The user interface of the node is similar to the script node, the user can either select an internal Text or load a file.
Internally, IES files are handled similar to Image textures: They are stored in slots by the LightManager and each unique IES is assigned to one slot.
The local coordinate system of the lamp is used, so that the direction of the light can be changed. For UI reasons, it's usually best to add an area light,
rotate it and then change its type, since especially the point light does not immediately show its local coordinate system in the viewport.

This commit adds number formatting (thousands separator) to the baking panel. It also adds a new function to format memory sizes (KB/GB/etc) and applies it to the baking panel and scene stats. The new function is unit tested.

Regression in recent undo system changes,
This caused T55048.
When each mode had its own undo stack it was important
to initialize it when entering edit-mode.
Since area lights are affected by scaling them, it only makes sense to support applying the scale to the lamp size.
Of course, applying location or rotation does not work.
If a scaling that changes the aspect ratio is applied to a square lamp, the mode is automatically changed to Rectangle.
This commit does two things:
- Adds an option to do the calculation in different color spaces (BT601
or BT709).
- Changes the default caluclation from legacy BT601 to BT709.
This affects several areas:
- UI areas (mainly scopes)
- ViewLevelsNode
- Several other nodes that use `COM_ConvertOperation.h`
Applied similar fix to T54233 to get the "Record with NLA" feature working with
active action blending + influence settings. Extrapolation is explicitly ignored
though, as it shouldn't be used with this feature (i.e. it is already disabled
with the new strips and also on the animdata by default)
