Implement writeStream method

[charisoudis]

When filesize is greater than 4Mib, write fails without a notice, i.e. returning true.
This PR, implements writeStream method and update write to use it when the file size exceeds that threshold.

Code heavily inspired by:
shitware-ltd/flysystem-msgraph

Your PR includes a call to $this->getFileBaseUrl() which doesn't exist. I borrowed your changes and got it to work by replacing that line with

return \sprintf('/v1.0/drives/%s/items/%s:/%s', $this->getConnector()->getDrive()->getDriveId(), $parentFolderId, $fileName)
