Conf parsing

[matteo-cristino]

Some zneroom config breaks the json logs format, for examaple

• debug=3 or higher
• logfmt=text

and breaking the json logs format brings to slngroom failing to execute the function

slangroom/pkg/ignored/src/index.ts

Lines 13 to 37 in 7c2951f

	export const getIgnoredStatements = async (
	contract: string,
	params: ZenParams,
	): Promise<string[]> => {
	// Since we want to get the list of ignored statements, we don't want to
	// throw if Zenroom execution fails (but we do fail if something other than
	// that happens). When Zenroom fails, the ZenroomError type's message
	// contains the logs.
	let logs: string[];
	try {
	// TODO: the zencodeExec() call could potentially be optimized, as
	// zencodeExec() parses the output result. Keep in mind: optimization bad.
	const zout = await zencodeExec(contract, params);
	logs = JSON.parse(zout.logs);
	} catch (e) {
	// Currently, only ZenError is available.
	// Normally, I'd let this code be, but we're trying to achieve 100%
	// coverage, so my "future-proof" code needs to be commented out here.
	// if (!(e instanceof ZenroomError))
	// throw e;
	logs = JSON.parse(e.message);
	}
	const regexIgnored = /(?<=\[W\] Zencode line [0-9]+ pattern ignored: ).*/;
	return logs.flatMap((log) => log.match(regexIgnored) || []);
	};

Thus slangroom should parse the conf in input and return an error in case one of the above conf is found
