Fix type of FormatListN template parameter (#74)

jrohel · web-flow · commit b08ca66c7311 · 2020-04-17T17:34:10.000+10:00
The fix changes type of FormatListN template parameter from int to std::size_t.

Without the fix and with strict gcc compiler settings we get:
tinyformat.h:1019:21: error: conversion from ‘long unsigned int’ to ‘int’ may change value [-Werror=conversion]
 1019 | detail::FormatListN&lt;sizeof...(Args)&gt; makeFormatList(const Args&amp;... args)
