Add options for whether to fetch posts and skills data

[endernoke]

Is your feature request related to a problem? Please describe.
Users should be able to configure whether they only want the ingest of the basic profile or include posts, skills, etc. data (which require another API call to LinkedIn).
This may speed up the loading duration significantly if the user is only interested in one section of the profile.

Describe the solution you'd like
A section next to the search bar with fetching configurations.
Alternatively, split profile, posts, skills fetching into separate calls to the backend, so data can be fetched upon request.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
