Possibly showing incorrect estimated saving from database

Using Version 4.0 Beta 5

I'm a little confused, the estimation numbers being displayed don't match neither the data found in the "Compression DB" tab or the database json.

Example:

A Short Hike

It's mixing the numbers:

Estimated saving percentage for XPRESS8K (27%) in database -> Shown under LZX in folder scan
Estimated saving percentage for LZX (31%) in database -> Shown under XPRESS16K in folder scan

Adiditionally, in the database json only one estimation is available:

242310177 bytes -> 231.1MB (I think ?)
"CompType":1 -> XPRESS8K

From the information above, I think that:

The data found in the Compression DB tab is correct, although I don't understand where the LZX data is coming from, unless the program uses a different data source
The estimated savings for game scans is assigning the incorrect estimates data to compression types

I think this is an example that can clearly tells what is incorrect:

Database Compression	Shown as in Folder Scan
XPRESS4K	XPRESS4K ❎
XPRESS8K	LZX ❌
XPRESS16K	XPRESS8K ❌
LZX	XPRESS16K ❌

Good catch, I think it's because I'm using two different mappings throughout the program (which I really shouldn't do) and got them wrong for the buttons. The buttons should use CompressionMode but I've incorrectly used WOFComperssionAlgorithm

public enum CompressionMode: int
{
    XPRESS4K = 0,
    XPRESS8K = 1,
    XPRESS16K = 2,
    LZX = 3,
    None = 4
}


public enum WOFCompressionAlgorithm: int
{
    NO_COMPRESSION = -2,
    LZNT1 = -1,
    XPRESS4K = 0,
    LZX = 1,
    XPRESS8K = 2,
    XPRESS16K = 3
}

Windows uses the second one internally so I need to convert between the two and I keep mixing them up haha. I'll fix this soon :)

Fix compression buttons not showing the correct estimation values. Fixes
