allow more online models to load tokens file from the memory

[shawl336]

for online paraformer and ctc, their symbol tables are able to be initialized from tokens in a memory buffer

[shawl336]

for the keywords spotter example, the kws model failed to spot any keywords among the given test wavs. however, if i record a wav myself, only the @你好军哥 can be spotted, could u help check the keywords-spotter-buffered-tokens-keywords-c-api.c, I can not figure the problem, other than imputing it to the model accuray

[shawl336]

the check "test-nodejs / test-nodejs (ubuntu-latest, 3.8) (pull_request)" failed due to the wasm filesystem, both keywords_file and keywords_buf are provided, which did not pass the validate().
should i add a special case for wasm in the validate or change the test code for the wasm filesystem (i am not familiar to wasm)

Please check the keywords contained in the keywords.txt and check whether the test wave file contains a keyword.

my mistake, I confused with the test_wavs/test_keywords.txt and the keywords.txt, now the keywords can be spotted out

Please focus only on the C++ and C APIs. I will fix the errors related to other programming language APIs.

Thanks! Looks good to me. Only left some minor comments.

[shawl336]
