"JLCPCB Library" shall display a better Description

[bvernoux]

In "JLCPCB Library" display add the Description from https://github.com/yaqwsx/jlcparts/blob/master/LCSC-API.md (instead of the ones from https://jlcpcb.com/parts) as the one from https://jlcpcb.com/parts is unreadable and not accurate

• Maybe first step will be to "parse/extract/display" correctly the "LCSC Description" from the csv as it is not displayed correctly today.
• Example screenshot with issue (°C ... not displayed correctly ...) on Description

I fixed "incorrect description" with 0ce0c3d
The encoding of the CSV is gbk rather than iso-8859-1

As this is kind of the same issue / enhancement as #16 I'll go to work out a solution over there and use it in bth, the main window and the library.

I confirm all work fine with Windows10 + KiCad Nightly (r24220)
