sysclk-lwla: Add firmware extraction script for LWLA1016

Provide a simple shell script which extracts byte ranges from the
Windows software. Note that this only works on an installation of
the original software, since the firmware files are not as easily
extractable directly out of the installer executable.

+sigrok\-fwextract\-sysclk\-lwla1016 \- Extract SysClk LWLA1016 firmware
+.SH "SYNOPSIS"
+.B sigrok\-fwextract\-sysclk\-lwla1016 LWLA1016-INST-DIR
+.SH "DESCRIPTION"
+This tool extracts FPGA bitstreams from the vendor software for the SysClk
+LWLA1016 USB logic analyzer. Install the original software (possibly within
+a virtual machine) and locate the installation directory.
+.PP
+In order to extract the bitstreams, run the following command:
+.PP
+.B "  $ sigrok-fwextract-sysclk-lwla1016 INSTALL-DIR"
+.PP
+Copy the resulting four bitstream files over to the location where libsigrok
+expects to find its firmware files. By default this is
+.BR /usr/local/share/sigrok-firmware .
+.SH OPTIONS
+None.
+.SH "EXIT STATUS"
+Exits with 0 on success, 1 on most failures.
+.SH "SEE ALSO"
