missing microseconds for TIME_INPUT_FORMATS

[Stephan Groß]

there are no microseconds in the valid input formats.

the current settings are:

TIME_INPUT_FORMATS = (
    '%H:%M:%S',     # '14:30:59'
    '%H:%M',        # '14:30'
)

and could be:

TIME_INPUT_FORMATS = (
    '%H:%M:%S',     # '14:30:59'
    '%H:%M:%S.%f',     # '14:30:59.000200'
    '%H:%M',        # '14:30'
)
