Reconnect on session timeout

Fixes #855

Hi, @MariusWirtz , I assume this new re_auth method is reusing the same session id?

I imagine you would only call the re_auth function when your session is already invalidated.
The below script has a new session_id after the re_auth.

from TM1py import TM1Service

tm1 = TM1Service(base_url="https://localhost:12354", user="admin", password="apple")
print(tm1.connection.session_id)

# imagine this logout happens naturally after a long wait time through HttpSessionTimeout on TM1 side
tm1.logout()

tm1.re_connect()

print(tm1.connection.session_id)
