Column type coercion to boolean from tinyint stopped working in 1.2.10

Issue Description

I have a couple of boolean columns in a MySQL source defined as tinyint that I coerced into bool in my Postgres target using source_options, but this seems to have stopped working after upgrading to 1.2.10. (worked on 1.2.9 and doesn't work on either 1.2.10 or 1.2.11)

Description of the issue:

In my replication config I'm adding source options to the MySQL source tables like this:

    source_options:
      columns:
        myFirstColumn: bool
        mySecondColumn: bool
        myThirdColumn: bool

These columns are TINYINT in MySQL, containing 0, 1 and possibly NULL as values. Columns were correctly coerced to boolean in my Postgres target before 1.2.10, now they are VARCHAR(65500).

Sling version (sling --version): 1.2.11
Operating System (linux, mac, windows): linux (docker)
Replication Configuration:

can't share the full config, the defaults are pretty simple, everything is set up on stream level

defaults:
  object: staging.{stream_table}

  target_options:
    column_casing: snake

...
