remove type casting to allow addDynamicTemplateData to accept arrays.

[timstl]

Hello,

I have a set of dynamic data that includes both strings and arrays. Here's a sample of that data:

array (
  'sender' => 
  array (
    'firstName' => 'John',
    'fullName' => 'John doe',
    'email' => 'john@example.com',
  ),
  'state' => 'Colorado',
  'residence' => 'Nonresident',
  'year' => 2022,
  'licenses' => 
  array (
    0 => 
    array (
      'name' => 'Stamp',
      'cost' => '$10.59',
    ),
    1 => 
    array (
      'name' => 'Annual License',
      'cost' => '$86.50',
    ),
  ),
) 

I'm not sure if there's a better way to handle this, but type casting $value as a string was causing an error with the 'licenses' key, an array. Once removed, the data passed successfully to SendGrid and populated the template as expected.

Hi @timstl,

You're right! The underlying library does support other data types.
I'm going to this and create a new release. Thank you!
