PHP 8 compatibility

[Rudloff]

This repository does not seem to support PHP 8 and Composer 2:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires fxp/composer-asset-plugin ^1.4.2 -> satisfiable by fxp/composer-asset-plugin[v1.4.2, ..., v1.4.6].
    - fxp/composer-asset-plugin[v1.4.2, ..., v1.4.6] require composer-plugin-api ^1.0 -> found composer-plugin-api[2.3.0] but it does not match the constraint.
  Problem 2
    - hiqdev/hisite dev-master requires hiqdev/hidev-webapp dev-master -> found hiqdev/hidev-webapp[dev-master] but it does not match your minimum-stability.
    - hiqdev/hisite[0.0.1, ..., 0.1.0] require php ^5.6|^7.0 -> your php version (8.1.12) does not satisfy that requirement.
    - Root composer.json requires hiqdev/hisite <2.0 || dev-master -> satisfiable by hiqdev/hisite[dev-master, 0.0.1, 0.0.2, 0.0.3, 0.1.0].

Are there any plans to update the requirements?
