* removal of `omo` command
* use of `oml`, `oml.` and `oml=` to list maps instead of `om`
* removal of RIZIN output from `oml`
* removal of `omn.` and just assume `omn` uses core->offset
* Use PJ in `oj`
* Replace `r_cons_printf()` and other minor fixes
* Fix output and add a basic test for `oij`
* Use `pj_kb` in writable and raised
* Move `pj_new()` and `pj_a()` outside the loop
* Fix \`oij\` by creating a new PJ array before the case begins, add the objects, and print and free it at the end of the function.
