These keyboards lack dedicated multimedia keys.

I've tested the FX support on a g512 and all command work just fine with
the exception of not being able to set a logo color simply because there
is no backlit logo…

This patch just updates the help notice which mentions that the FX
commands are only tested on the g810, suggesting that they might not
work on other keyboards.

Raw use of 0xFF as the effectpart byte is device-undefined and was
implemented as a wrapper around mutliplle native effects calls as well
as handling the indicators. Logic was previously implemented in the
application, allowing for library use in this particular case to have
undefined behavior.

Help output does not need to initialize a device, so rearrange
the parsing to check for help commands prior to performing
any device IO.

Change argument parsing to segregate options from the command

Add -dv -dp and -ds options to allow matching a vendor ID, device ID,
and/or device serial number.

Modify --list-keyboards to parse the DeviceInfo vector and output
information to stdout.

Purpose for this is for command argument parsing of vendor and product
IDs

Allow filtration and matching of specified Device ID, Product ID, Serial
Number

Fix an issue in listKeyboards (hidapi) with an out of bounds search when
using serial number

Fix possible null reference problem in listKeyboards (hidapi) that
caused rare segfaults when traversing the device enumeration in
increments of two

Fix handling of output of listKeyboards (hidapi) where it was
incrementing the dev list pointer, then accessing the node to look for
device serial number (potential security risk)

Fix handling of serial number output of listKeyboards (hidapi) to handle
wchar_t instead of outputting the memory address

Fix issue in listKeyboards (libusb) failure to finish cleaning up USB
contexts, leading to a segfault if calling a separate function after
listing keyboards.

Fix issue in close (libusb) segfaulting if m_hidHandle was null, so
added a check.

Modify listKeyboards to provide a vector of DeviceInfo objects that can
be used by calling applications instead of outputting to stdout directly.

Implement a struct to hold information regarding device information and
ability for a library caller to query this information to make decisions
about the currently targeted device.

Specified version string in makefile will now propogate to VERSION as a
macro appended to CFLAGS.

Cleaned up version string, quotes not necessary when specifying
major/minor/micro, though this is purely cosmetic.
