Lua 5.3 scripts: problem with '>>'

[alex85k]

I am using ESPLorer to experiment with newer NodeMCU firmware built with make LUA=53

There are problems when code includes newly introduced right shift operator >> like

a=7
b=a>>3

When saving the script to flash the process hangs and module reboots. The problem is in these 2 lines of code checking the
module answer:

ESPlorer/src/main/java/ESPlorer/ESPlorer.java

Line 12038 in 142ff90

data = data.replace(">> ", "");

   data = data.replace(">> ", "");
   data = data.replace(">>", "");

(I commented them for myself, it seems to work)

As Lua 5.3 will become the standard sooner or later (see nodemcu/nodemcu-firmware#3144 (comment) from @TerryE) this should be addressed.
