Support symfony/filesystem v7.0

[kriptogenic]

I'm getting this error while installing:

composer require mhor/php-mediainfo ^5.5
The "5.5" constraint for "mhor/php-mediainfo" appears too strict and will likely not match what you want. See https://getcomposer.org/constraints
./composer.json has been updated

Problem 1
- Root composer.json requires mhor/php-mediainfo 5.5 -> satisfiable by mhor/php-mediainfo[5.5.0].
- mhor/php-mediainfo 5.5.0 requires symfony/filesystem ~3.4|~4.0|~5.0|~6.0 -> found symfony/filesystem[v3.4.0-BETA1, ..., 3.4.x-dev, v4.0.0-BETA1, ..., 4.4.x-dev, v5.0.0-BETA1, ..., 5.4.x-dev, v6.0.0-BETA1, ..., 6.4.x-dev] but the package is fixed to v7.0.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

Thanks @kriptogenic for opening an issue, this package is now compatible with symfony/process:^7.0 and symfony/filesystem:^7.0.

Fixed into #148
Released as 5.6.0
