Building windows crashes for certain icon sizes

[Endaris]

In love-exedit.lua in line 382, newdata which is FileData userdata is overwritten by a string if it turns out that the resized icon from the build config is bigger than lvl3_entry.DataSize.
The application then crashes in line 386 because it tries to call FileData:getString on what is no longer FileData.
Wrapping line 382 in a newFileData solves the crash but I have no immediate access to a Windows machine right now to confirm the exe icon is also correct afterwards so I'm opening an issue instead of a PR.
Used icon for repro:

Ah nice, will have a look - i know there's less space to play with now in 12 but should still be able to get it working

Okay made some changes to the code in 0.7 - haven't done a release for it yet but seems to at least not crash with that icon now

Seperately seems to be an issue with the zip files for 12.0 source for any of the builds newer than this one:

Seems to either be an issue with the zip being made, or maybe a change to love.data.decompress, not 100% what's going on

Going to try and investigate that more first so I can check the new 0.7 changes in latest 12 first before releasing
