Text OSD with 31+ characters has issues

Hi,

For rts_osd2_type_text when the string buffer has more than 31 characters, the trailing characters are not printing sometimes and total text ignored if more than 36+ characters are available.

The OSD demo provided ameba-rtos-pro2/component/video/osd2/isp_osd_example.c at main · Ameba-AIoT/ameba-rtos-pro2 · GitHub has string buffer of length 64, but it is not printing properly if we keep more than 31 characters.

Please provide an update with fix for this issue and also OSD text with black color showing black rectangles instead of characters - #8 by yugandhar

Thanks
