Description

When creating a DataPart object, $encoding parameter is limited to 'quoted-printable', 'base64' or '8bit' by this code in TextPart.php:

if ('quoted-printable' !== $encoding && 'base64' !== $encoding && '8bit' !== $encoding) {
    throw new InvalidArgumentException(sprintf('The encoding must be one of "quoted-printable", "base64", or "8bit" ("%s" given).', $encoding));
}

We are missing the possiblity to set a binary encoding to create OData batch request, as each part must have a binary encoding (https://docs.oasis-open.org/odata/odata/v4.0/errata02/os/complete/part1-protocol/odata-v4.0-errata02-os-part1-protocol-complete.html#_Toc406398359) : A MIME part representing an individual request MUST include a Content-Type header with value application/http and a Content-Transfer-Encoding header with value binary.

From MIME RFC1341 (https://www.w3.org/Protocols/rfc1341/5_Content-Transfer-Encoding.html) it seems binary is just like 8bit, but without any line-length limit.

How to reproduce

new DataPart($bodyAsString, null, 'application/http', 'binary');

throws the above exception

InvalidArgumentException('The encoding must be one of "quoted-printable", "base64", or "8bit" ("binary" given).');

Possible Solution

Maybe it's possible to treat "binary" as an alias of "8bit"
