Dasel: Denial of service in dasel selector lexer due to infinite loop on unterminated regex literal

Summary dasel's selector lexer enters a non-terminating loop when tokenizing an unterminated regex pattern such as r/abc. A 2-byte input r/ is sufficient to cause the tokenizer to consume 100% CPU on one core indefinitely. I confirmed the issue on v3.3.1 fba653c7f248aff10f2b89fca93929b64707dfc8 a...
