alter_context like in j2cli

[pkalemba]

Hi,

I'm migrating away from the unmaintained j2cli tool, but my use case involves a specific environment. I’ve been leveraging the j2 command with the --customize option, where I define a function utilizing the alter_context feature to manipulate the rendering context dynamically.

After reviewing the documentation , I couldn’t find a comparable option or feature.
Is there a recommended approach to achieve similar functionality in jinjanator ?

I just opened #46 to add this functionality, lets see if it will be accepted :-)
