Fava 1.26.2 breaks fava _investor

[CJKohler]

when trying to import fava_investor, I get the following error:

 
File "/Beancount/.venv/lib/python3.11/site-packages/fava_investor/common/favainvestorapi.py", line 2, in <module>
    from fava.template_filters import cost_or_value
ImportError: cannot import name 'cost_or_value' from 'fava.template_filters' (/Beancount/.venv/lib/python3.11/site-packages/fava/template_filters.py)

When I look in Fava 1.26 the cost_or_value function is there, but it is gone in 1.26.1 and 1.26.2
pip3 install --force-reinstall fava==1.26
Now at least I can import fava_investor without problems.

Another issue is the fact that _charts.html has been removed from Fava after 1.25 which causes the following error:
File "/Beancount/.venv/lib/python3.11/site-packages/fava_investor/templates/Investor.html", line 2, in top-level template code {% import "_charts.html" as charts with context %} ^^^^^^^^^^^^^^^^^^^^^^^^^ jinja2.exceptions.TemplateNotFound: _charts.html

Thanks for filing this. I've fixed requirements.txt to reflect this.

There are at least a couple tickets on getting fava_investor to be compatible with new versions of fava. I just haven't had the time to make the fixes needed. PRs welcome, else I should be able to get to it in a few weeks.

See #84. This should be fixed now.
