Add create_status_cols function

[andysontran]

Partial fix for issue #21

• Functionalized initialization of sawmill_pass and sawmill_status columns in timber at the start of the check_grain function

• Added to-do notes for build_chairs function

• Updated .gitignore to include .DS_Store

• Still need to implement in all submill functions (i.e., under mill.R: read_timber, debark, etc.?)

Looks good to me.
Unclear what triggered the update to sawmill.rd (perhaps bump to Roxygen?).
I haven't tested with timber.

Thanks for reviewing Brennan!

I think you're right about the bump to Roxygen since the version number changed in sawmill.rd.

I haven't tested with timber.

Testing with example timber for all four grain types produces an error following the Reorder Fields function.

Error in value[3L] : ERROR in sawmill function:
Error in value[3L]: ERROR in Reorder Fields: reorder processed timber output columns. function:
Error in timber_del[field_names] at sawmill/R/reorder_fields.R:61:3:
! Can't subset columns that don't exist.
✖ Columns ID_meta and insensible_prev_table don't exist.

Not sure if you're experiencing the same error in the latest merge to main.
