Stefan Weil 3452c8ebee Fix out-of-bounds writes in Classify::ReadNewCutoffs 
The function did not correctly read Chinese unichars into the local
Class variable if the locale was set to de_DE.UTF-8 (or other
incompatible locales). That resulted in a wrong ClassId which was
used to write into the Cutoffs array without checking for valid bounds.

On macOS the result was a runtime error in baseapi_test (see GitHub
issue #1250):

    [ RUN      ] TesseractTest.InitConfigOnlyTest
    baseapi_test(21845,0x1134c45c0) malloc: *** error for object 0x927f96c28005e0: pointer being freed was not allocated
    baseapi_test(21845,0x1134c45c0) malloc: *** set a breakpoint in malloc_error_break to debug

Replacing sscanf by std::istringstream fixes that.
Add also an assertion to catch future out-of-bounds writes.
