Upgrade corrade and magnum to fix vs2022 compilation errors

[ghidosoft]

I tried to compile NoiseTool using VS2022 but I got some compilation errors in ImageProperties.h in the Magnum library.

I simply changed the GIT_TAG of corrade and magnum and it compiles and runs apparently fine (just for the records I used d44ca683c12ed28fce1d27662f24edee2d7e2c6a for corrade and a218ddfa9434201aaca207ea9c8e87fea91a0757 for magnum).
I don't know if those revisions are OK for you, I simply took the last commit on master. Shall I make a PR?

Thanks
