Introducing Ne2000 driver

[sirbu12]

i had also made the documentation for it located at x16-PRos/docs/Drivers/Ne2000.md
and a ping command too:

ping.asm: the ping command. usage: ping IPv4 address
ne2000.inc: included file inside all apps that has to do with networking (rignt now only ping.asm), includes the driver itself inside the app source code as a set of functions to be called from the app source code.

also please note: i am still a begginer at git because the cloned repo i worked from includes a splash screen but the original repo ( github.com/prox2011/x16-pros ) has another splash screen.

for now, all the networking protocols is needed to be implemented manually in the app because the driver only has the code to talk with the NIC itself, not any protocol.

In the future:
i will try to add IPv6 ( if possible in 16 bit )
protocols so each app won't have to

In case of changes needed, i hope the reviewer ( PRoX2011 ) will text me in telegram or right here in the comments
