Fix jq parse error on special chars

[wllm-rbnt]

This is a fix for the following error (example query taken from README.md):

$ dig +short -t TXT 931606baaa7a2b4ef61198406f8fc3f4.dns.hashlookup.circl.lu | jq -r . | jq . parse error: Invalid string: control characters from U+0000 through U+001F must be escaped at line 2, column 34

$ dig +short -t TXT 931606baaa7a2b4ef61198406f8fc3f4.dns.hashlookup.circl.lu | jq -j . | jq . { "CRC32": "13C49389", "FileName": "./bin/ls", "FileSize": "133792", "MD5": "931606BAAA7A2B4EF61198406F8FC3F4", "OpSystemCode": "362", "ProductCode": "217853", "SHA-1": "D3A21675A8F19518D8B8F3CEF0F6A21DE1DA6CC7", "SHA-256": "0D06F9724AF41B13CDACEA133530B9129A48450230FEEF9632D53D5BBB837C8C", "SpecialCode": "" }

"jq -j ." does not add an extra line return for split records:

$ dig +short -t TXT 931606baaa7a2b4ef61198406f8fc3f4.dns.hashlookup.circl.lu | jq -r . {"CRC32": "13C49389", "FileName": "./bin/ls", "FileSize": "133792", "MD5": "931606BAAA7A2B4EF61198406F8FC3F4", "OpSystemCode": "362", "ProductCode": "217853", "SHA-1": "D3A21675A8F19518D8B8F3CEF0F6A21DE1DA6CC7", "SHA-256": "0D06F9724AF41B13CDACEA133530B91 29A48450230FEEF9632D53D5BBB837C8C", "SpecialCode": ""}

$ dig +short -t TXT 931606baaa7a2b4ef61198406f8fc3f4.dns.hashlookup.circl.lu | jq -j . {"CRC32": "13C49389", "FileName": "./bin/ls", "FileSize": "133792", "MD5": "931606BAAA7A2B4EF61198406F8FC3F4", "OpSystemCode": "362", "ProductCode": "217853", "SHA-1": "D3A21675A8F19518D8B8F3CEF0F6A21DE1DA6CC7", "SHA-256": "0D06F9724AF41B13CDACEA133530B9129A48450230FEEF9632D53D5BBB837C8C", "SpecialCode": ""}%
