Add a way to set file type in `get_asset_info` function

wp-framework/src/Assets/GetAssetInfo.php

Lines 64 to 75 in 4512e0b

	if ( file_exists( $this->dist_path . 'js/' . $slug . '.asset.php' ) ) {
	$asset = require $this->dist_path . 'js/' . $slug . '.asset.php';
	} elseif ( file_exists( $this->dist_path . 'css/' . $slug . '.asset.php' ) ) {
	$asset = require $this->dist_path . 'css/' . $slug . '.asset.php';
	} elseif ( file_exists( $this->dist_path . 'blocks/' . $slug . '.asset.php' ) ) {
	$asset = require $this->dist_path . 'blocks/' . $slug . '.asset.php';
	} else {
	$asset = [
	'version' => $this->fallback_version,
	'dependencies' => [],
	];
	}

If a JS and CSS use the same handle, it might load incorrect asset PHP data.
because it always check js first.

maybe:

get_asset_info( $file_dir, $slug, $attribute = null )

Or include the dir in the slug:

get_asset_info( 'css/file' )
get_asset_info( 'js/file' )
