fix "@param foo[in/out]" to "@param[in, out] foo"

Fix a few invalid doxygen comments:

    /**
     * @param[in,out] correctly_formatted
     * @param incorrect1[in] - [in] must come immediately after @param
     * @param incorrect2[in/out] - '/' must be ','
     */

Actual command: sed -i -e "s/\(\* .*param\)\( [^\[]*\)\(\[.*\]\)/\1\3\2/g" -e "s/in\//in,/" $( git grep -l "\* .*param .*\[\(in\|out\)" )
