Add explicit dependency on isaac >= 0.1.2

Something depends on isaac 0.1.0, but that version doesn't compile on Nim 0.16
and above. Until the transitive dependancy is updated, ask for at least 0.1.2.

+# Personal Time Keeper
+
+`ptk` is a small utility to log time entries. It uses a simple conceptual model
+and a simple JSON data format.
+
+A ptk timeline is made up of a series of ptk entries, or marks. Each mark has a
+summary, a timestamp, and a universally unique id (generated by `ptk`).
+Additionally a mark may be tagged with an arbitrary number of tags and may have
+detailed notes attached to it (anything representable in plain text).
+
+The duration of a task is calculated by taking the difference between that
+task's timestamp and the one following it chronologically. The `STOP` value as
+a summary serves as a sentinal to indicate that an entry has been completed
+and no new entry is being tracked.
