MIPS API pcsx_putc only output after newline

[Sirithang]

Describe the bug

Unsure if this is a bug or just undocumented behaviour, but when i try to user pcsx_putc to output to the console (both in logs and when redirecting to stdout) it will only appear after you putc a newline \n

e.g.

pcsx_putc('c');
pcsx_putc('d');

won't output anything but

pcsx_putc('c');
pcsx_putc('d');
pcsx_putc('\n');

will output cd in the console

Expected behavior

Either it should output each character or if it require a newline to "submit" all character queue till then, this should be added to the documentation

Steps to reproduce the bug

Use the pcsx_putc function in any source code compiling to psexe. This was tested in one of the basic example of https://github.com/spicyjpeg/ps1-bare-metal
