[BUG] parseArray不能忽略空的值，而是抛出异常

com.alibaba.fastjson2.JSONException: offset 28, character ,, line 1, column 28, fastjson-version 2.0.52 [[21976997982896132,1000,0,,,0]]

对这个[[21976997982896132,1000,0,,,0]]进行parseArray的时候，在fastjson1中，是会忽略连续的几个逗号的，但是在fastjson2中，会抛出异常，实际上这几个逗号，可能是代表没有值，有没有办法回到fastjson1中的行为（忽略逗号，只匹配有值的数）

Start by reproducing the parseArray failure with [[21976997982896132,1000,0,,,0]] and compare it with fastjson1 behavior. Trace the parseArray entry point and existing parser tests, then verify that consecutive empty values are ignored and populated numeric values still parse correctly.
