Pass svg_checks.sh via ShellCheck

while read svgfile; do
    SC2162: read without -r will mangle backslashes.

if [ $(wc -c < "$svgfile") -gt $(wc -c < "$outfile") ];
    SC2046: quote to prevent word splitting

found increment was done in a subshell and hence would not be properly
incremented. Instead of:

  find | while

Switch to:

  while < <( find )

Based on https://github.com/koalaman/shellcheck/wiki/SC2031 , this way
$found is kept in the same context.
