Failed to compile on esp-idf due to set method.

[GioTB]

I´m using the library on esp-idf on a esp32, and i´m having the following error on compile:

TinyGPSPlus/src/TinyGPS++.cpp:487:10: error: 'char* strncpy(char*, const char*, size_t)' specified bound 16 equals destination size [-Werror=stringop-truncation]
strncpy(this->stagingBuffer, term, sizeof(this->stagingBuffer));

has i can see the strncpy on the Set method should have a "-1" size so the destination buffer always contains the null character.
For now i modified it to compile by leaving the strncpy like this:

void TinyGPSCustom::set(const char *term)
{
strncpy(this->stagingBuffer, term, sizeof(this->stagingBuffer) - 1);
}
i hadded the "-1" on the size parameter, i saw the stagingBuffer and i realized that it´s size it´s +1 of _GPS_MAX_FIELD_SIZE wich i suppose it´s precisely for the null character so there shouldn´t be any problem.

If this is right, please add it to the repo!

Thanks!!!!

There is a buffer overflow security problem here if _GPS_MAX_FIELD_SIZE could ever be exceeded on the input, so (size-1) on the strncpy 3rd arg is always good hygiene. As this repo seems to have gone inactive I'm going to grab @GioTB 's fork and use that.
