New version of MathematicalSystems

TagBot does not trigger anymore. Maybe wake it up?

EDIT: The build error in v1.8 x86 seems unrelated:

InexactError: trunc(Int32, -1.0507929548530072e199)

Thanks, there are updates to do in the examples as well

[schillic]

Done! But there is a new build error on v1.8.3:

ERROR: LoadError: Wrapping `Vararg` directly in UnionAll is deprecated (wrap the tuple instead).
[...]
ERROR: LoadError: Failed to precompile MappedArrays

Again I think this is independent of this PR.

About the error:
MappedArrays.jl has not seen an update since over a year. Maybe consider replacing this dependency or ask about the status of the open PR that tries to fix this warning (now error).

I deactivated depwarn: error on CI to fix the build. @blegat let me know what you think.

Thanks!
