By supplying `bulletpoints_show = False` to the experience function,
the bullet points under each work experience heading will be
entirely removed so only the work experience names themselves
remain. Good for a general CV, or non-american style listings.
Added simple creation of motivation letter to make outputs.
Uses quarto just like the cv creation, using the letter.qmd
file as its base. Will be included in running a general
`make` command.
Added motivation letter template, originally from a DIN letter
by benedictdudel, slightly adjusted to work with the yaml
frontmatter of quarto (e.g. `to` had to be adjusted).
Whenever an empty section was encountered we returned `None`
which lead to display artifacts as Quarto tried to interpret
what we actually wanted to display.
Instead, we simply return an empty string which is to be
'displayed' so nothing will be shown.
Now newly required since they may appear in an environment not cleaned by
pandoc and smartypants (since they can appear in code blocks for xcolor
commands now).
Pandoc would use smartypants to make a variety of font elements and ligatures pretty,
while the used CV template always fell back to TeX T1 font, missing all kinds of
these symbols.
