digitemp: init at 3.7.2

This does not include digitemp_DS2490, as that seems to require libusb0.1,
which isn't in nixpkgs.

+      DigiTemp is a command line application used for reading 1-wire sensors like
+      the DS18S20 temperature sensor, or DS2438 battery monitor. DigiTemp supports
+      the following devices:
+
+        DS18S20 (and older DS1820) Temperature Sensor
+        DS18B20 Temperature Sensor
+        DS1822 Temperature Sensor
+        DS2438 Battery monitor
+        DS2409 1-wire coupler (used in 1-wire hubs)
+        DS2422 Counter
+        DS2423 Counter
+
+      The output format can be customized and all settings are stored in a
+      configuration file (.digitemprc) in the current directory. DigiTemp can
+      repeatedly read the sensors and output to stdout and/or to a logfile.
