Supply chain issue due to hyperx/ercent-encoding

[achimcc]

This package depends on hyperx, and hyperx is imposing upper bounds on outdated dependencies. In my case, I can't use it in my project any longer together with other packages:

error: failed to select a version for `percent-encoding`.
    ... required by package `hyperx v1.0.0`
    ... which satisfies dependency `hyperx = "^1"` of package `hubcaps v0.6.2`
    ... which satisfies dependency `hubcaps = "^0.6.2"` of package `backend v0.1.0 (/home/achim/projects/ink-playground/crates/backend)`
    ... which satisfies path dependency `backend` of package `generate-bindings v0.1.0 (/home/achim/projects/ink-playground/crates/generate-bindings)`
versions that meet the requirements `>=2.1.0, <2.2` are: 2.1.0

The issues have been reported to hyperx several times: https://github.com/dekellum/hyperx/issues/39 However, the maintainer seem not to care about them.
