Support CEL in Pepr

[cmwylie19]

Is your feature request related to a problem? Please describe.

Regex is slow, and Kubernetes now supports CEL, which has regex built in but it is interpreted quicker due to the backend. This would require Go but we already support WASM and that could theoretically be passed to the Go code for interpretation

https://kubernetes.io/docs/reference/using-api/cel/#kubernetes-regex-library

Describe the solution you'd like

• Given a user creates a binding that includes CEL
• When the binding filters are being interpretted
• Then it is the Go code that interprets the CEL

Describe alternatives you've considered

(optional) A clear and concise description of any alternative solutions or features you've considered.
