Unwanted Behavior when one checkbox is checked

Code automatically checked the "check-all" box if any one of the checkboxes is checked (line 87 in src/index.ts)

Proposed change: replace with the following if statement

if ((total - count) == 0) {
setChecked(target, allCheckbox, checked, indeterminate);
}

Start at line 87 in src/index.ts and inspect how the total and checked counts determine the check-all state. Change the condition so the check-all box is set only when all checkboxes are checked, then verify that selecting one checkbox no longer checks it while selecting all still does.
