Fails to build (dependency disregarded semver)

[luiswirth]

Description
wgpu-core fails to build, because one of it's dependency did a breaking change without adhering to semantic versioning.

The crate gpu-alloc fixed a typo ("treshold" => "threshold"), which was a breaking change and only increased the minor version number. Therefor Cargo updated automatically to the newest version.

Repro steps
Do a cargo update and see how the newest version of gpu-alloc 0.3.1 doesn't work with wgpu-core 7.1

Expected vs observed behavior
I expected it to build :).

Platform
Arch-Linux x86
