Add json format output.

[M09Ic]

Cleaned up the code and solved multiple problems in pr #163

The specific changes compared to #163:

• delete jsonline format, combine to one json per line.
• now it will not destroy the original behavior.
• add source fields to json output.
• fixed some issues you pointed out in pr 163
• if set -j/--json flag, auto enable clean output(output json data only, ignore other data)

example1:

echo 1.1.1.1 | ./nali.exe -j | jq
{
  "type": 0,
  "ip": "1.1.1.1",
  "text": "澳大利亚 APNIC/CloudFlare公共DNS服务器",
  "source": "qqwry",
  "info": {
    "country": "澳大利亚",
    "area": "APNIC/CloudFlare公共DNS服务器"
  }
}

If we need to output the database name, I recommend using the real database name defined in the configuration file, because the user may modify it, and the same database format may have multiple sources and therefore may have different names.

nali/internal/db/type.go

Lines 16 to 17 in 748c5cf

	type DB struct {
	Name string

- name: geoip2
  format: mmdb
  file: GeoIP2-City.mmdb
- name: geolite2
  format: mmdb
  file: GeoLite2-City.mmdb
- name: ipinfo
  format: mmdb
  file: ipinfo_country.mmdb
- name: dbip
  format: mmdb
  file: dbip.mmdb

Has been changed to return the same value for dbif.Name func as db.Name field.
