Mouse wheel step on Phantomsdr+ v2.0.0 (quick fix)

[9a7aof]

Hello everyone,

In version 2.0.0 the normal mouse wheel step is missing.

I found the files that define it, edited them and made an npm run build.

I set the default step to 1kHz, the others are in the drop-down menu when you click on the micro icon in the top right.

It would be normal for me if this option was right below or above the Fine Tuning menu. It is too important a function to be buried in some drop-down menu. 

Attached are my edited files, if you are interested you can install them instead of the original ones and made an npm run build.

It took me more than five hours to figure out where I needed to edit,
the author could do it in three minutes if he wanted. 

ServerInfo.svelte is in /PhantomSDR-Plus/frontend/src/components/
frequencySteps.js is in /PhantomSDR-Plus/frontend/src/stores/
App.svelte is in /PhantomSDR-Plus/frontend/src/

Wheel step.png show "normal" wheel step after I editing ServerInfo.svelte and frequencySteps.js

Best Regards,
