iconv: fix missing bounds checking for shift_jis decodingHEADmaster
the jis0208 table we use is only 84x94 in size, but the shift_jis encoding supports a 94x94 grid. attempts to convert sequences outside of the supported zone resulted in out-of-bounds table reads, misinterpreting adjacent rodata as part of the character table and thereby converting these sequences to unexpected characters.
