Loads a PEM file.

    :param contents: the contents of the file to interpret
    :param pem_marker: the marker of the PEM content, such as 'RSA PRIVATE KEY'
        when your file has '-----BEGIN RSA PRIVATE KEY-----' and
        '-----END RSA PRIVATE KEY-----' markers.

    :return: the base64-decoded content between the start and end markers.

    @raise ValueError: when the content is invalid, for example when the start
        marker cannot be found.
