Release version 0.4.2

* Fix macOS shared memory filename length limit

Shorten shared memory object names from "__tdf_kittage_{pid}_page_{rn}_{page_num}"
to "tdf_{pid}_{rn}_{page_num}" and change timestamp from nanoseconds to
milliseconds % 1M to stay under macOS's 31-character limit for shm names.

Fixes "File name too long (os error 63)" error when rendering PDFs on macOS.

On macOS, SHM_NAME_MAX: 30
