fix(deno): set isDeno to false if version > 1.45.2

[sc0Vu]

I think we shouldn't use self. after Deno 1.45.3., based on their comment denoland/deno#24726 (comment), Deno had followed the NodeJs behavior.

In this PR, I added simple comparison from semver (compare major / minor / patch).

# deno version
~/ccxt$ deno -v
deno 1.46.3

# before
~/ccxt$ deno -A binance-fetch-ohlcv-many-symbols-async-await.js
error: Uncaught (in promise) ReferenceError: self is not defined
    at file:///home/ubuntu/ccxt/node_modules/.deno/[email protected]/node_modules/ccxt/js/src/base/ws/WsClient.js:14:48

# patch
~/ccxt$ cp ../platform.js /home/ubuntu/ccxt/node_modules/.deno/[email protected]/node_modules/ccxt/js/src/base/functions
~/ccxt$ cp ../misc.js /home/ubuntu/ccxt/node_modules/.deno/[email protected]/node_modules/ccxt/js/src/base/functions

# after

TODO:

• checked why the script stuck.
  something wrong happened in node-fetch, it stuck everytime......

The node-fetch seems not work well in deno. I'm gonna find another way to fix this.
