Using pudb as an API

Hello,

I would like to use pudb as an API, to integrate it with my favorite editor kakoune.

I was wondering if there is a way to use it more or less like this:
```python
file_to_debug = pudb.load('foo.py')

# adding breakpoint to line 3 of foo.py
file_to_debug.add_breakpoint(3)

# being able to use command next, continue and step into
file_to_debug.continue() # should stop at the next breakpoint ( line 3 )

# being able to retrieve data from the right side panel
file_to_debug.get_variables() # getting all variables loaded at line 3
file_to_debug.get_stack()

```
