Changed 'aria2c --version' to 'LANG=en_US.UTF-8 aria2c --version' for consistent environment

[kei1-st]

In my environment, $LANG=ja_JP.UTF-8 is set by default and the output of aria2c --version is in Japanese.

In that case, the value of the aria2Ver is "aria2 バージョン" instead of "aria2 version", which does not match versionRegex = RegExp(/aria2 version (. *)/) and followiing process throws an error.

destreamer/src/Utils.ts

Lines 216 to 229 in e93ad80

	try {
	const versionRegex = new RegExp(/aria2 version (.*)/);
	const aira2Ver: string = execSync('aria2c --version').toString().split('\n')[0];
	if (versionRegex.test(aira2Ver)) {
	logger.verbose(`Using ${aira2Ver}\n`);
	}
	else {
	throw new Error();
	}
	}
	catch (e) {
	process.exit(ERROR_CODE.MISSING_ARIA2);
	}

To solve this problem, change execSync('aria2c --version') to execSync('LANG=en_US.UTF-8 aria2c --version') so that the output of the command aria2c --version is always in English.
