DynamoGeek and nao-pon Fixes a (very unlikely to be hit) bug that'll cause a failure to up… (#…

* - Fixes a (very unlikely to be hit) bug that'll cause a failure to upload if the passed in resource is the exact same length as the chunk size
- Fixes a bug where chunk size wasn't being detected as a multiple of 262,144B (256KB), causing a failure to upload
- Fixes a bug where out of memory errors are likely when working with larger files due to chunk size being based on the memory limit, rather than the remaining available memory

* Updated the order of variables in a method call to be correct.

* Updated to move $client->setDefer(true) before create/update of the Drive file to prevent a fatal error.

* correction to use `setDefer(true)` and chunk size

After all, using `getFileObject ()` after using `setDefer (true)` make a problem, so I fixed. In addition, the calculation method of the chunk size is also corrected. This commit solves all problems I know of.

	[ 'useHasDir' => true ]             // options (elFinder need hasDir method)

// Extended cached strage adapter class for cache enabled of hasDir() method
class myCachedStrageAdapter extends \League\Flysystem\Cached\Storage\Adapter
    use \Hypweb\Flysystem\Cached\Extra\Hasdir;
    use \Hypweb\Flysystem\Cached\Extra\DisableEnsureParentDirectories;

// Make Flysystem adapter and cache object
$useCache = true;

		new \League\Flysystem\Adapter\Local('flycache'),

	// Flysystem cached adapter
	$adapter = new \League\Flysystem\Cached\CachedAdapter(
} else {
	// Not use cached adapter
	$cache = null;
	$adapter = $googleDrive;

// Google Drive elFinder Volume driver
$gdrive = [
    // require
    'driver'       => 'FlysystemExt',
    'filesystem'   =>  new \League\Flysystem\Filesystem($adapter),
    'fscache'      => $cache,

    'rootCssClass' => 'elfinder-navbar-root-googledrive'

// elFinder volume roots options
$elFinderOpts = [
	'roots' => []

$elFinderOpts['roots'][] = $gdrive;

// run elFinder
