* include/fmt/format.h: int_writer: removed unnecessary iterator type re-declaration (prevents shadow-waringing in clang)
* include/fmt/format.h: int_writer: correctly cast signed integer to unsigned to prevent 'implicit conversion changes signedness'-warnings in clang.

Get rid of conversion warning in gcc-4.8
Get rid of the following warning:
conversion to ‘int’ from ‘long unsigned int’ may alter its value [-Werror=conversion]
* Remove conversion compiler warning
When compiling with g++8, I get the following two errors:
include/fmt/format-inl.h:400:29: error: conversion from ‘int’ to ‘char’ may change value [-Werror=conversion]
buffer[size++] = zero + static_cast<char>(digit);
~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~
include/fmt/format-inl.h:416:28: error: conversion from ‘int’ to ‘char’ may change value [-Werror=conversion]
buffer[size++] = '0' + digit;
~~~~^~~~~~~
With this change, the errors are gone.
