some numeric literals could be more compact

minor optimization...

$ esbuild --version
0.3.5

$ echo 'console.log(0.00001234)' | esbuild --minify
console.log(1.234e-05);

$ echo 'console.log(0.00001234)' | terser
console.log(1234e-8);

$ echo 'console.log(123400000)' | esbuild --minify
console.log(1.234e08);

$ echo 'console.log(123400000)' | terser 
console.log(1234e5);
