Make python api work

[DhanshreeA]

Closes #1449

This PR aims to make the Python API, ie the ErsiliaModel class work as intended, ie through a synchronous API, without the keyword async. To that effect, the API now looks like:

(ersilia) ☁  ~  python
Python 3.10.13 (main, Aug  1 2024, 16:45:21) [Clang 15.0.0 (clang-1500.3.9.4)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from ersilia import ErsiliaModel
>>> em = ErsiliaModel("molecular-weight")
>>> em.fetch()
>>> em.serve()
>>> em.run("CCCCC")
<generator object ErsiliaModel._api_runner_iter at 0x131df52a0>
>>> res = list(em.run("CCCCC"))
>>> res
[{'input': {'key': 'OFBQJSOFQDEBGM-UHFFFAOYSA-N', 'input': 'CCCCC', 'text': 'CCCCC'}, 'output': {'value': 72.151}}]
>>>

A model can also be fetched outside of the ErsiliaModel, using the ModelFetcher class as follows:
