Support for FreeRTOS lxip specifier

[sdc-andy]

In the FreeRTOS-TCP network stack they use the custom specifier %lxip which is passed an IP address as a uint32_t and aims to print it as a xxx.xxx.xxx.xxx format.

Can this be added?

If you were to ask me this question about my active fork, I would answer negatively, because the idea is to be standard-compliant; and exceptions are POSIX-defined specifiers like%t for ptrdiff_t. For a platform-specific format specifier, you probably want to create your own repository based on this one.
