read_pdb_from_list() not containing newlines

[uros-sipetic]

Describe the bug

When reading in PDB content via read_pdb_from_list(), the text itself does not contain newlines where they should be, thus making any future commands like
pdb_lines = ppdb.pdb_text.split("\n")
not work properly (as after splitting, a list with just 1 huge element is returned, the element being the entire PDB content

Steps/Code to Reproduce

ppdb = PandasPdb().read_pdb(input_pdb)
pdb_lines = ppdb.pdb_text.split("\n")
new_ppdb = PandasPdb().read_pdb_from_list(pdb_lines)
new_pdb_lines = new_ppdb.pdb_text.split("\n")

Expected Results

I would expect the last line in the above code to create a list of all the lines in the PDB file.

Actual Results

The output of the last line in the above code is a list with just 1 element, the element being the entire PDB content as one string
