bioparser.hpp: support Gcc 10
bioparser.hpp: support Gcc 10

If I understand correctly https://gcc.gnu.org/gcc-10/porting_to.html, the header would need to include explicitely stdexcept, otherwise attempting to build programs using bioparser.hpp will fail to locate the definition of the multiple occurrences of std::invalid_argument.

This patch allows to move forward with building bioparser based tools with Gcc 10.
