Bug: Candid encoding not correctly assigning different variants for a `key: variant val` vector

for some reason dfx and didc is not working correctly for encoding a vec with the value which is a variant of different types

For simplicity, I stripped the argument down to only the offending structure, and provide an example with didc (didc 0.1.4) which is enough to replicate the issue

didc decode \
   "$(didc encode '(
      vec {
          record { "name"; variant { TextContent = "blah" } };
          record { "ttl"; variant { Nat64Content = 1 : nat64 } };
      }
   )')"

running this will give you an error:

Error: Trailing value after finishing deserialization

Caused by:
    input: 4449444c036d016c02007101026b01ecbfa8c90d71010002046e616d650004626c61680374746c000100_000000000000
    table: type table0 = vec table1
    type table1 = record { text; table2 }
    type table2 = variant { 3_643_416_556 : text }
    wire_type: text, expect_type: text

Which it seems to encode everything as that first type it comes across, instead of corresponding variants, as seen by table2

Meta

dfx --version:

dfx 0.11.2

didc --version:

didc 0.1.4

Start by running the provided didc encode/decode reproduction with dfx 0.11.2 and didc 0.1.4, focusing on the vec of records containing differently typed variants. Trace the Candid type-table and deserialization path implicated by the error. Done means the example decodes successfully and preserves the TextContent and Nat64Content variant types.
