Remove dependency to logging system

[filchos]

The code in website/lib/make_xlsx.py uses methods that access the database of the logging system, e.g. by using the function get_data.

The import statement for these functions however is commented out:

#from website.database.get_data import get_data, get_personnel_list, get_cruise

Since template generator should be completely independent from the logging system, no DB calls should be executed in the function.

Instead of

def do_something(DB=None):
    data = get_data(DB …)
    do_stuff(data)

do_something(DB)

This can help to make the template generator more self-containing:

def do_something(data):
    do_stuff(data)

data = get_data(DB …)
do_something(data)

• [ ] check, if the lines that access the DB can be removed
• [ ] if not: check, how this information can be injected from the outside instead of accessed from the inside.
