seek-to: Add support for dot separated timestamps

Nothing to add here, the code is fully his.
To quote from the original commit message:

    For best results use at least 3 digits for milliseconds (.000) or
    a full timestamp HH.MM.SS.sss (00.00.00.1):

    00.11.31.527
    11.11.11.2
    1.23.11.5
    00.61.611
    11.30.527
    11.30.000
    61.61 (this will be treated as 1m1s610ms)
