Update wiki about KEY_RESIZE

[gdm85]

I have been looking into #32 and #34 regarding the event KEY_RESIZE not firing.

I suggest adding this information to the wiki page KnownIssues (I do not have rights to do that).

A new approach that I found out to be working (despite Go's limitations with the signal handler) is to compile the Go program with go build -buildmode=c-shared and then link the .so file in a C program that handles the getch() loop.

KEY_RESIZE will then be synthesised correctly.
