Yukihiro "Matz" Matsumoto 403b75fbeb fp_uscale.c: clamp parser underflow guard to POW10_MIN ...

mrb_read_float's underflow short-circuit used `final_p < -342 - nd`,
which for nd > 1 can be below POW10_MIN (-343). That let
parse_decimal call prescale() with a final_p below POW10_MIN, causing
an out-of-bounds read of pow10_tab. Tighten the guard to
`final_p < POW10_MIN`; values below that threshold cannot be
represented as a non-zero double for any mantissa within the parser's
19-digit cap.

Reported by OSS-Fuzz (testcase 6097379597287424).
