[raudio] Rewritten `ExportWaveAsCode()` file saving to be more like rtextures `ExportImageAsCode()` (#3013)

* Update raudio.c

Review `raudio.c`: rewritten `ExportWaveAsCode()` to be more like rtextures.c `ExportImageAsCode()'

* no tab november

accidentally inserted a tab somewhere. corrected it.
