If I do a bulk-load of many columns and many values, and then one of the values fail validation, the corresponding exception does not mention the concerned column name and neither the erroneous value. This makes it unnecessarily difficult to narrow down the wrong value that failed validation.

Describe the preferred solution
In https://github.com/tediousjs/tedious/blob/master/src/bulk-load.ts#L188 please add the c.name and also the value to the exception object that is returned. For example by simply adding more properties:

error.column = c.name
error.wrongValue = value

The section of the code would then read:

    try {
      value = c.type.validate(value, c.collation);
    } catch (error: any) {
      error.column = c.name
      error.wrongValue = value
      return callback(error);
    }

Of course you are free to add this information to any other of the properties, or even append it to the message. The main point is that these two bits of information should be added to the exception in any form.

Describe alternatives you've considered
hm... the exception here is pretty much exactly the normal error handling. It is simply missing the information about the place where the exception occurred.
