FieldInfo type is missing `length` property

[GingerAdonis]

The documentation has a type-casting example like below. But the column argument doesn't have the length property typed, which is probably a mistake.

const typeCastFunction = (column, next) => {
  if (column.type == "TINY" && column.length === 1) {
    const val = column.int();
    return val === null ? null : val === 1;
  }
  return next();
};

And a more generic question: Wouldn't it make sense to refactor the whole project to Typescript to prevent this and other typing mistakes from occurring?

Thanks for pointing that out, documentation has been corrected with this commit, see result.

Column have no length property, but columnLength

Additionally, decoding functions have been added to documentation.

TypeScript would have been a solution at the beginning. This would be a big refactor that is not on a schedule for now.
