AppImage mksquashfs binary does not support LZO compression

[om26er]

The mksquashfs binary is too old (https://github.com/electron-userland/electron-builder-binaries/blob/master/AppImage/linux-x64/mksquashfs), it does not support lzo compression, please build it with LZO compression and publish a new version.

Background: I am trying to enable electron-builder to support LZO compression for snap packages https://github.com/electron-userland/electron-builder/pull/6201 and I recently found that electron builder internally uses the mksquashfs binary from this repository. Below are the logs

Binary needs to be built with LZO_SUPPORT=1 https://github.com/plougher/squashfs-tools/blob/master/squashfs-tools/Makefile#L51

ping maintainers, is there a way I could help fix that ?
