cython3 need mentioning in the dependencies

[hzeller]

When running the compile as in the README, the following failure happens:

$ python3 setup.py test
Traceback (most recent call last):
  File "/home/hzeller/src/fasm/setup.py", line 28, in <module>
    from Cython.Build import cythonize
ModuleNotFoundError: No module named 'Cython'

So in the apt install line, it would then require cython3

Then, the setup test runs but it still fails with some other issue, please advise:

  File "/home/hzeller/src/fasm/setup.py", line 265, in <module>

TypeError: 'str' object is not callable

Since the stacktrace is a bit hard to read as Python reverses it, here a bit more digestable:

I have no idea what is happening here, does it mean there is an issue in loader.py in the local installation ?

I also figured out that we need to sudo apt install pkg-config and sudo pip3 install textx on a fresh Ubuntu 22.04 to build and install from the source.
Note that Cython could be installed either from apt (as you mentioned) or sudo pip3 install Cython.
