### New Features
- add `parse::section::header::is_valid_subsection()` function.
It can be useful to validate subsection names without having to
construct an entire `Header` (which also includes a name).
- Add various methods to iterate sections along with their id, and mutate them.
As section names are not unique, it was previously not possible to
iterate sections and then mutate them as one wouldn't be able to refer
to the exact section that was just traversed, after all, there can be
many sections named `remote "origin"`.
With the new methods it's possible to uniquely refer to each section
for mutation and removal.
### Bug Fixes
- greatly improve whitespace handling when removing values.
Previously, newlines would remain past a value, and whitespace could
remain before one.
Now both are removed to simulate removing an actual line.
- `File::remove_section()` was fixed to allow re-adding a similarly named section.
We also add `File::remove_section_by_id()` to make it possible to remove
specific sections.
