CodeQL warning: Wrong type of arguments to formatting function (CWE-686)

[tjko]

I noticed that CodeQL is flagging following:

main/build/_deps/picotool-src/main.cpp:2876
This format specifier for type 'int' does not match the argument type 'unsigned long'.
This format specifier for type 'int' does not match the argument type 'unsigned long'.

main/build/_deps/picotool-src/main.cpp:5267
This format specifier for type 'int' does not match the argument type 'fpos<__mbstate_t>'.

main/build/_deps/picotool-src/main.cpp:5365
This format specifier for type 'int' does not match the argument type 'fpos<__mbstate_t>'.

main/build/_deps/picotool-src/main.cpp:6565
This format specifier for type 'int' does not match the argument type 'unsigned long'.

Proposed fix: #274
