Adding icortex as a dependency

[osolmaz]

In a project that has Python version:

python = "^3.10"

Adding icortex to the project raised the following error.

The current project's Python requirement (>=3.10,<4.0) is not compatible with some of the required packages Python requirement:
  - icortex requires Python >=3.8,<3.11, so it will not be satisfied for Python >=3.11,<4.0

Because no versions of icortex match >0.1.1,<0.2.0
 and icortex (0.1.1) requires Python >=3.8,<3.11, icortex is forbidden.
So, because ... depends on icortex (^0.1.1), version solving failed.

Make sure icortex can be added in such cases.
