Reciepe for conan

[nicraMarcin]

@embeddedmz This is nice ftpclient and I think it would be nice to add it as reciepe to conan repo Conan.
What do you think?

Thank you. I don't know 'Conan' (I do know vcpkg though) and I can't really find free time to take care of my github projects during these troubled times both personally and externally.

Regards.

Conan is something what we was waiting for long times :)

@embeddedmz I can prepare and develop conan's recipe, but I think that sould be option to build tests in main CMakeLists.txt.
There also shluld be relases and library version.

Hi @embeddedmz, I wrote a conan recipe in #30 and maybe you can find time to check if it can be merged?
