"datetimes()" now generates "tricky" datetimes more often: values on or near daylight-saving and other utc-offset transitions of the drawn timezone - including imaginary wall times, and ambiguous ones with each value of "fold" - as well as times adjacent to leap seconds and to well-known datetimes like the millennium and the end of the signed 32-bit Unix epoch (issue [#69]).

This release also fixes some rare internal errors, where an error raised partway through updating an internal cache - for example by a deeply recursive strategy raising "RecursionError" - could leave that cache corrupted.
