(feat) fast agi: decode errors

[zt50tz]

Hello!

Sometimes, asterisk can pull truncated data to agi request. Something like this:

b'agi_network: yes\nagi_network_script: call_income\nagi_request: agi://127.0.0.1:4574/call_income\nagi_channel: SIP/*****-00011487\nagi_language: en\nagi_type: SIP\nagi_uniqueid: 1648407597.170145\nagi_version: 16.17.0\nagi_callerid: ****\nagi_calleridname: \xd0\x90\xd0\xbb\xd0\xb5\xd0\xba\xd1\x81\xd0\xb5\xd0\xb9, Volkswagen Passat, K129\xd0\nagi_callingpres: 0\nagi_callingani2: 0\nagi_callington: 0\nagi_callingtns: 0\nagi_dnid: 74991166525\nagi_rdnis: *****\nagi_context: macro-dial-ringall-predial-hook\nagi_extension: s\nagi_priority: 1\nagi_enhanced: 0.0\nagi_accountcode: \nagi_threadid: 140011921778432\nagi_arg_1: 302-303-304-306-307-308-309-310-311-312-313-314-315-320-321-323-329-339-340-341-342-318-346-347-348-349-10091-331-350'

So, if we try just to decode — it throws UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd0 in position 310: invalid continuation byte.

Will be nice to pass decode errors argument like .decode("utf-8", errors="ignore") to decode pass much well (than exception):

'agi_network: yes\nagi_network_script: call_income\nagi_request: agi://127.0.0.1:4574/call_income\nagi_channel: SIP/*****-00011487\nagi_language: en\nagi_type: SIP\nagi_uniqueid: 1648407597.170145\nagi_version: 16.17.0\nagi_callerid: ****\nagi_calleridname: Алексей, Volkswagen Passat, K129\nagi_callingpres: 0\nagi_callingani2: 0\nagi_callington: 0\nagi_callingtns: 0\nagi_dnid: 74991166525\nagi_rdnis: *****\nagi_context: macro-dial-ringall-predial-hook\nagi_extension: s\nagi_priority: 1\nagi_enhanced: 0.0\nagi_accountcode: \nagi_threadid: 140011921778432\nagi_arg_1: 302-303-304'

I add one more parameter to avoid this situation:

fast_agi.Application(decode_errors="ignore")

• May be AMI connection need this extension too. I use only AGI. If you find this PR helpfull I can add this lines to AMI.
• May be it can be "ignore" by default.

Thank you for your library!

The PR looks fine but it looks like tests are freezing on github actions. Cant be merged until the problem persist
