asleep 0.4.0

Now requires the asleep Python module version 0.5.0 or higher (from PyPI).
asleep() now passes sample_rate to asleep. If not specified, it uses attr(file, "sample_rate"); if neither is set, the sample rate is inferred.
Times returned by asleep() are the recorded clock times without a time zone; they are no longer shifted for non-UTC data or by the system time zone, and clock times in a daylight-saving gap are kept. For data.frame input, attr(result, "tzone") gives the time zone of file$time. times, sleep_windows and sleep_windows_long are now character clock times too; they were POSIXct that displayed in the system time zone.
dplyr (>= 1.2.0) is now in Imports; asleep() always uses it. lubridate moved to Suggests.
sample_rate no longer has to be an integer (e.g. GENEActiv 85.7 Hz).
sl_write_csv() writes time stamps to the microsecond; rounding to the millisecond made the sample interval of non-integer-rate data irregular.
