compilation issues with latest arduino ide

Trying to use this library with the latest Arduino IDE 1.8.13 results in the error:

SparkFun_LED_8x7.cpp:637: undefined reference to `operator delete(void*, unsigned int)'

There seems to be a problem with how the 'delete' operator is defined.  Opening SparkFun_LED_8x7.cpp and changing the line:

delete chaplex_;

to

free(chaplex_);

fixes the issue.
