Score Calculation QOL

[sakurada0291]

This is considered a QOL feature request; the reason why I write this is most TJAs put the 2nd value after the 1st valure of SCOREINIT: and it shows an error.

Explanation:
TJAs that are published back 2010s onwards tend to use SCOREINIT and SCOREDIFF as they adhere to the old scoring system, for Gen 2 arcades and up to Gen 3 (being 2011 version until Green).

Example of videos:
"Red Rose Evangel" has an inital score of 420, and it multiplies by 1 in 10 to 29th combo, 2 in 30 to 49th combo, 3 in 50 to 99th combo, and 4 in 100 combo and so on. The boost for each step is 98, and the example of the said formula is elaborated below:

コンボ	計算式	得点
1-9コンボ	420＋98×0	420 = 420点
10-29コンボ	420＋98×1	518 = 510点
30-49コンボ	420＋98×2	616 = 610点
50-99コンボ	420＋98×4	812 = 810点
100コンボ以降	420＋98×8	1204 = 1200点

Note: they are rounded off to the nearest tens.

Example:
Formula is SCOREINIT:X,Y and either let Y or the whole SCOREINIT and SCOREDIFF command can be erased.
Most TJAs end up written in SCOREINIT:2030,450. If SCOREINIT and SCOREDIFF are blank, TSE can automatically calculate for Shinuchi (真打), the de jure scoring method of Nijiiro scoring system
