enlarge COL_MODE from varchar(10) to varchar(12)

[dg9vh]

If you take a look at http://www.adif.org/304/ADIF_304.htm#Mode_Enumeration you'll see, that "DIGITALVOICE" is a valid mode in ADIF-Specification with length of 12 chars, COL_MODE only allows varchar(10), so we need 2 additional characters there to produce valid logs in ADIF.

Oddly I hit that issue today I just made a change request on the PR sir once change is done i'll add it.

You might need to add similar for sub_mode
