Folder names might be invalid

When I tried to download S02 from https://www.bbc.co.uk/iplayer/episodes/m0015167/marcus-wareings-tales-from-a-kitchen-garden freevine properly downloaded the stream but was not able to store it, as the MPD(?) apparently had a after the end of the name, and Windows foldernames cannot have a blank as the last character. So the folder was created w/o the blank and the subsequent steps to mux failed with "File not found". You can clearly see the additional " " at the end of the directory path in the stacktrace.

To Reproduce

(.venv) F:\freevine>freevine.py get --season  s02 https://www.bbc.co.uk/iplayer/episodes/m0015167/marcus-wareings-tales-from-a-kitchen-garden  -sv res=720

Expected behavior freevine can handle even erraneous filenames.

Suggestion is to strip() all names/paths so in case something is unexpected it won´t affect the filesystem naming.
