/**

* Servicio: checksumService
|
|
*
|
|
* Calcula sumas y metadatos de un fichero de forma eficiente usando streams.
|
|
* Las funciones principales procesan el archivo en streaming para producir:
|
|
* - `md5` (hex)
|
|
* - `sha1` (hex)
|
|
* - `crc32` (hex, 8 caracteres)
|
|
* - `size` (bytes)
|
|
*
|
|
* `computeHashes(filePath)` devuelve un objeto con los valores anteriores y
|
|
* está pensado para usarse durante la importación/normalización de ROMs.
