Add estimation for the expires time for transferring large files

[bbbco]

Description

Sometimes the download I am trying will timeout while finishing to download because it is a very large file (multiple GBs). This change allows you to define a timeout with the expires attribute; otherwise it employs some basic math to determine how long to set the timeout.

@bbbco did you want us to be able to merge this? It seems reasonable, but we can't unless you legally permit us to by using a DCO Signed-off-by.
