Exporting godot signalR client

[Vitalii-Fynytskyi]

How to properly export the project with SignalR client? If launched from editor with Play button it works well. However in exported version It throws related to SignalR exception when client tries to connect to server. It requires data_[ProjectName] directory to be in the same directory where exported .exe file is located. In Windows I can just manually copy this catalog to exported .exe file. But in Android it is a problem because I can't write files to internal storage.
