Generate a Raven selection table from LFDCS autodetections

lfdcs_to_raven(
  lfdcs_file,
  raven_file = "selections.txt",
  audio_start_time,
  lfdcs_start_time = "1970-01-01 00:00:00",
  call_types = "",
  max_mdist = "",
  t_buff = 0.5,
  f_buff = 25
)

`lfdcs_file`	The autodetections generated by `export_autodetections`
`raven_file`	The desired name (.txt) of the Raven selection table
`audio_start_time`	String giving the audio start time (YYYY-mm-dd HH:MM:SS)
`lfdcs_start_time`	String giving the lfdcs start time (YYYY-mm-dd HH:MM:SS)
`call_types`	A vector of desired call types
`max_mdist`	A numeric value indicating the maximum Mahalanobis distance to export
`t_buff`	The time buffer (in seconds) that is added to the start and end of each selection. This helps make the selection more visible in Raven.
`f_buff`	The frequency buffer (in Hz) that is added to the top and bottom of each selection. This helps make the selection more visible in Raven.

The Low-Frequency Detection and Classification System (LFDCS) automatically detects marine mammal vocalizations in large datasets. This script converts a csv file of LFDCS autodetections (extracted from raw detector output using 'export_autodetections') into a text file that can be imported into Raven Pro as a selection table.
