Split Siglent driver off from LeCroyOscilloscope as they've diverged too much

[RX14]

I attempted to connect to an sds1104x-e with glscope client and got the following trace:

$ build/src/glscopeclient/glscopeclient --debug --trace SCPISocketTransport siglent:siglent:lan:192.168.0.232:5025

The programming guide for sds1/2xxx series scopes is available at https://siglentna.com/wp-content/uploads/2020/04/ProgrammingGuide_PG01-E02C.pdf

It appears that the LeCroy and Siglent drivers have diverged more than I thought.

We probably need to write a new Siglent driver that doesn't reuse any of the LeCroy code in order to handle the non-Windows CE based Siglent scopes.

Should be fixed in 8a88a06.
