[low priority] Inspect dependencies

[neurlang]

There is a lot of deps in go.mod which adds a lot of transitive dependencies to projects who import gorgonia/cu (like mine)

Try to inspect for what are these deps needed, and possibly eliminate them to shorten download time.

I would like to take a look at this.

part of this would also be to check if a newer dependency is available and bump the version.

• cyclic dependency - gorgonia depends on cu and cu depends on gorgonia
• cc is there twice (modernc.org and github.com/cznic is the same guy?)
• xc can be bumped to v1.1.0
• cc is horribly outdated, current version is like v4.21.2
• tensor can be bumped to v0.9.24
• gonum can be bumped to v0.15.0
• bindgen was never released? make at least v0.0.1 tag in bindgen?
• ...
